ALSA: hda - Fix path power activation
The widget power-saving code tries to turn up/down the power of each
widget in the I/O paths that are modified at each jack plug/unplug.
The recent report revealed that the power activation leaves some
widgets unpowered after plugging. This is because
snd_hda_activate_path() turns on path->active flag at the end of the
function while the path power management is done before that. Then
it's regarded as if nothing is active, and the driver turns off the
power.
The fix is simply to set the flag at the beginning of the function,
before trying to power up.

ASoC: topology: Update TLV support so we can support more TLV types
Currently the TLV topology structure is targeted at only supporting the
DB scale data. This patch extends support for the other TLV types so they
can be easily added at a later stage.
TLV structure is moved to common topology control header since it's a
common field for controls and can be processed in a general way.
Users must set a proper access flag for a control since it's used to
decide if the TLV field is valid and if a TLV callback is needed.
Removed the following fields from topology TLV struct:
- size/count: type can decide the size.
- numid: not needed to initialize TLV for kcontrol.
- data: replaced by the type specific struct.
Added TLV structure to generic control header and removed TLV structure
from mixer control.

ALSA: fireworks/firewire-lib: add support for recent firmware quirk
Fireworks uses TSB43CB43(IceLynx-Micro) as its IEC 61883-1/6 interface.
This chip includes ARM7 core, and loads and runs program. The firmware
is stored in on-board memory and loaded every powering-on from it.
Echo Audio ships several versions of firmwares for each model. These
firmwares have each quirk and the quirk changes a sequence of packets.
As long as I investigated, AudioFire2/AudioFire4/AudioFirePre8 have a
quirk to transfer a first packet with 0x02 in its dbc field. This causes
ALSA Fireworks driver to detect discontinuity. In this case, firmware
version 5.7.0, 5.7.3 and 5.8.0 are used.

i915: temporary fix for DP MST docking station NULL pointer dereference
Ted Ts'o reports that his Lenovo T540p ThinkPad crashes at boot if
attached to the docking station. This is a regression that he was able
to bisect to commit
8c7b5ccb7298: "drm/i915: Use atomic helpers for
computing changed flags:"
The reason seems to be the new call to drm_atomic_helper_check_modeset()
added to intel_modeset_compute_config(), which in turn calls
update_connector_routing(), and somehow ends up picking a NULL crtc for
the connector state, causing the subsequent drm_crtc_index() to OOPS.
Daniel Vetter says that the fundamental issue seems to be confusion in
the encoder selection, and this isn't the right fix, but while he chases
down the proper fix, this at least avoids the NULL pointer dereference
and makes Ted's docking station work again.

link_path_walk(): be careful when failing with ENOTDIR
In RCU mode we might end up with dentry evicted just we check
that it's a directory. In such case we should return ECHILD
rather than ENOTDIR, so that pathwalk would be retries in non-RCU
mode.
Breakage had been introduced in commit
b18825a - prior to that
we were looking at nd->inode, which had been fetched before
verifying that ->d_seq was still valid. That form of check
would only be satisfied if at some point the pathname prefix
would indeed have resolved to a non-directory. The fix consists
of checking ->d_seq after we'd run into a non-directory dentry,
and failing with ECHILD in case of mismatch.

stmmac: fix missing MODULE_LICENSE in stmmac_platform
Commit
50649ab14982 ("stmmac: drop driver from stmmac platform code")
was a bit overzealous in removing code and dropped the MODULE_*
macro's that are still needed since stmmac_platform can be a module.
Fix this by putting the macro's remvoed in
50649ab14982 back.
This fixes the following errors when used as a module:

to wake-up the system as wol_en is 0 (wake-on flag set to 'd').
Calling set_wakeup_enable() at netdev open is just redundant

gianfar: Fix suspend/resume for wol magic packet
If we disable NAPI in the first place we can mask the device's
interrupts (and halt it) without fearing that imask may be
concurrently accessed from interrupt context, so there's
no need to do local_irq_save() around gfar_halt_nodisable().
lock_rx_qs()/unlock_tx_qs() are just obsoleted and potentially
buggy routines. The txlock is currently used in the driver only
to manage TX congestion, it has nothing to do with halting the
device. With these changes, the TX processing is stopped before
gfar_halt().
Compact gfar_halt() is used instead of gfar_halt_nodisable(),
as it disables Rx/TX DMA h/w blocks and the Rx/TX h/w queues.
gfar_start() re-enables all these blocks on resume. Enabling
the magic-packet mode remains the same, note that the RX block
is re-enabled just before entering sleep mode.
Add IRQF_NO_SUSPEND flag for the error interrupt line, to signal
that the interrupt line must remain active during sleep in order
to wake the system by magic packet (MAG) reception interrupt.
(On some systems the MAG interrupt did trigger w/o this flag
as well, but on others it didn't.)
Without these fixes, when suspended during fair Tx traffic the
interface occasionally failed to be woken up by magic packet.

dmaengine: mv_xor: fix big endian operation in register mode
Commit
6f166312c6ea2 ("dmaengine: mv_xor: add support for a38x command
in descriptor mode") introduced the support for a feature that
appeared in Armada 38x: specifying the operation to be performed in a
per-descriptor basis rather than globally per channel.
However, when doing so, it changed the function mv_chan_set_mode() to
use:
if (IS_ENABLED(__BIG_ENDIAN))
instead of:
#if defined(__BIG_ENDIAN)
While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler. Consequently, the commit broke support for big-endian,
as the XOR_DESCRIPTOR_SWAP flag was not set in the XOR channel
configuration register.
The primarily visible effect was some nasty warnings and failures
appearing during the self-test of the XOR unit:

dmaengine: at_xdmac: fix transfer data width in at_xdmac_prep_slave_sg()
This patch adds the missing update of the transfer data width in
at_xdmac_prep_slave_sg().
Indeed, for each item in the scatter-gather list, we check whether the
transfer length is aligned with the data width provided by
dmaengine_slave_config(). If so, we directly use this data width for the
current part of the transfer we are preparing. Otherwise, the data width
is reduced to 8 bits (1 byte). Of course, the actual number of register
accesses must also be updated to match the new data width.
So one chunk was missing in the original patch (see Fixes tag below): the
number of register accesses was correctly set to (len >> fixed_dwidth) in
mbr_ubc but the real data width was not updated in mbr_cfg. Since mbr_cfg
may change for each part of the scatter-gather transfer this also explains
why the original patch used the Descriptor View 2 instead of the
Descriptor View 1.
Let's take the example of a DMA transfer to write 8bit data into an Atmel
USART with FIFOs. When FIFOs are enabled in the USART, its Transmit
Holding Register (THR) works in multidata mode, that is to say that up to
4 8bit data can be written into the THR in a single 32bit access and it is
still possible to write only one data with a 8bit access. To take
advantage of this new feature, the DMA driver was modified to allow
multiple dwidths when doing slave transfers.
For instance, when the total length is 22 bytes, the USART driver splits
the transfer into 2 parts:
First part: 20 bytes transferred through 5 32bit writes into THR
Second part: 2 bytes transferred though 2 8bit writes into THR
For the second part, the data width was first set to 4_BYTES by the USART
driver thanks to dmaengine_slave_config() then at_xdmac_prep_slave_sg()
reduces this data width to 1_BYTE because the 2 byte length is not aligned
with the original 4_BYTES data width. Since the data width is modified,
the actual number of writes into THR must be set accordingly.

dmaengine: at_hdmac: fix residue computation
As claimed by the programmer datasheet and confirmed by the IP designer,
the Block Transfer Size (BTSIZE) bitfield of the Channel x Control A
Register (CTRLAx) always refers to a number of Source Width (SRC_WIDTH)
transfers.
Both the SRC_WIDTH and BTSIZE bitfields can be extacted from the CTRLAx
register to compute the DMA residue. So the 'tx_width' field is useless
and can be removed from the struct at_desc.
Before this patch, atc_prep_slave_sg() was not consistent: BTSIZE was
correctly initialized according to the SRC_WIDTH but 'tx_width' was always
set to reg_width, which was incorrect for MEM_TO_DEV transfers. It led to
bad DMA residue when 'tx_width' != SRC_WIDTH.
Also the 'tx_width' field was mostly set only in the first and last
descriptors. Depending on the kind of DMA transfer, this field remained
uninitialized for intermediate descriptors. The accurate DMA residue was
computed only when the currently processed descriptor was the first or the
last of the chain. This algorithm was a little bit odd. An accurate DMA
residue can always be computed using the SRC_WIDTH and BTSIZE bitfields
in the CTRLAx register.
Finally, the test to check whether the currently processed descriptor is
the last of the chain was wrong: for cyclic transfer, last_desc->lli.dscr
is NOT equal to zero, since set_desc_eol() is never called, but logically
equal to first_desc->txd.phys. This bug has a side effect on the
drivers/tty/serial/atmel_serial.c driver, which uses cyclic DMA transfer
to receive data. Since the DMA residue was wrong each time the DMA
transfer reaches the second (and last) period of the transfer, no more
data were received by the USART driver till the cyclic DMA transfer loops
back to the first period.

net: sched: fix refcount imbalance in actions
Since commit
55334a5db5cd ("net_sched: act: refuse to remove bound action
outside"), we end up with a wrong reference count for a tc action.
Test case 1:
FOO="1,6 0 0
4294967295,"
BAR="1,6 0 0
4294967294,"
tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 \
action bpf bytecode "$FOO"
tc actions show action bpf
action order 0: bpf bytecode '1,6 0 0
4294967295' default-action pipe
index 1 ref 1 bind 1
tc actions replace action bpf bytecode "$BAR" index 1
tc actions show action bpf
action order 0: bpf bytecode '1,6 0 0
4294967294' default-action pipe
index 1 ref 2 bind 1
tc actions replace action bpf bytecode "$FOO" index 1
tc actions show action bpf
action order 0: bpf bytecode '1,6 0 0
4294967295' default-action pipe
index 1 ref 3 bind 1
Test case 2:
FOO="1,6 0 0
4294967295,"
tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action ok
tc actions show action gact
action order 0: gact action pass
random type none pass val 0
index 1 ref 1 bind 1
tc actions add action drop index 1
RTNETLINK answers: File exists [...]
tc actions show action gact
action order 0: gact action pass
random type none pass val 0
index 1 ref 2 bind 1
tc actions add action drop index 1
RTNETLINK answers: File exists [...]
tc actions show action gact
action order 0: gact action pass
random type none pass val 0
index 1 ref 3 bind 1
What happens is that in tcf_hash_check(), we check tcf_common for a given
index and increase tcfc_refcnt and conditionally tcfc_bindcnt when we've
found an existing action. Now there are the following cases:
1) We do a late binding of an action. In that case, we leave the
tcfc_refcnt/tcfc_bindcnt increased and are done with the ->init()
handler. This is correctly handeled.
2) We replace the given action, or we try to add one without replacing
and find out that the action at a specific index already exists
(thus, we go out with error in that case).
In case of 2), we have to undo the reference count increase from
tcf_hash_check() in the tcf_hash_check() function. Currently, we fail to
do so because of the 'tcfc_bindcnt > 0' check which bails out early with
an -EPERM error.
Now, while commit
55334a5db5cd prevents 'tc actions del action ...' on an
already classifier-bound action to drop the reference count (which could
then become negative, wrap around etc), this restriction only accounts for
invocations outside a specific action's ->init() handler.
One possible solution would be to add a flag thus we possibly trigger
the -EPERM ony in situations where it is indeed relevant.
After the patch, above test cases have correct reference count again.

Merge branch 'r8152-fixes'
Hayes Wang says:
====================
r8152: device reset
v3:
For patch #2, remove cancel_delayed_work().
v2:
For patch #1, remove usb_autopm_get_interface(), usb_autopm_put_interface(), and
the checking of intf->condition.
For patch #2, replace the original method with usb_queue_reset_device() to reset
the device.
v1:
Although the driver works normally, we find the device may get all 0xff data when
transmitting packets on certain platforms. It would break the device and no packet
could be transmitted. The reset is necessary to recover the hw for this situation.

r8152: add pre_reset and post_reset
Add rtl8152_pre_reset() and rtl8152_post_reset() which are used when
calling usb_reset_device(). The two functions could reduce the time
of reset when calling usb_reset_device() after probe().
