ASoC: core: fix devres parameter in devm_snd_soc_register_card()
Since devm_card_release() expects parameter 'res' to be a pointer to
struct snd_soc_card, devm_snd_soc_register_card() should really pass
such a pointer rather than the one to struct device.
This bug causes the kernel Oops below with imx-sgtl500 driver when we
remove the module. It happens because with 'card' pointing to the wrong
structure, card->num_rtd becomes 0 in function soc_remove_dai_links().
Consequently, soc_remove_link_components() and in turn
soc_cleanup_codec[platform]_debugfs() will not be called on card
removal. It results in that debugfs_card_root is being removed while
its child entries debugfs_codec_root and debugfs_platform_root are still
there, and thus the kernel Oops.
Fix the bug by correcting the parameter 'res' to be the pointer to
struct snd_soc_card.

PTE_PROT_NONE means that a pte is present but does not have any

pgprot_writecombine() is allowed and such bits overlap with

ALSA: hda - Check leaf nodes to find aamix amps
The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself. But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls. This is a regression
compared with the previous static quirks.
This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.

md/raid5: fix newly-broken locking in get_active_stripe.
commit
566c09c53455d7c4f1 raid5: relieve lock contention in get_active_stripe()
modified the locking in get_active_stripe() reducing the range
protected by the (highly contended) device_lock.
Unfortunately it reduced the range too much opening up some races.
One race can occur if get_priority_stripe runs between the
test on sh->count and device_lock being taken.
This will mean that sh->lru is not empty while get_active_stripe
thinks ->count is zero resulting in a 'BUG' firing.
Another race happens if __release_stripe is called immediately
after sh->count is tested and found to be non-zero. If STRIPE_HANDLE
is not set, get_active_stripe should increment ->active_stripes
when it increments ->count from 0, but as it didn't think it was 0,
it doesn't.
Extending device_lock to cover the test on sh->count close these
races.
While we are here, fix the two BUG tests:
-If count is zero, then lru really must not be empty, or we've
lock the stripe_head somehow - no other tests are relevant.
-STRIPE_ON_RELEASE_LIST is completely independent of ->lru so
testing it is pointless.

cgroup: fix cgroup_subsys_state leak for seq_files
If a cgroup file implements either read_map() or read_seq_string(),
such file is served using seq_file by overriding file->f_op to
cgroup_seqfile_operations, which also overrides the release method to
single_release() from cgroup_file_release().
Because cgroup_file_open() didn't use to acquire any resources, this
used to be fine, but since
f7d58818ba42 ("cgroup: pin
cgroup_subsys_state when opening a cgroupfs file"), cgroup_file_open()
pins the css (cgroup_subsys_state) which is put by
cgroup_file_release(). The patch forgot to update the release path
for seq_files and each open/release cycle leaks a css reference.
Fix it by updating cgroup_file_release() to also handle seq_files and

The source of this problem is that SCSI hosts are removed from
ATA ports after calling ata_tport_delete() which removes the
port's sysfs directory, among other things. Now, after commit
bcdde7e221a8, the sysfs directory is removed along with all of
its subdirectories that include the SCSI host's sysfs directory
and its subdirectories at this point. Consequently, when
device_del() is finally called for any child device of the SCSI
host and tries to remove its "power" group (which is already
gone then), it triggers the above warning.
To make the warnings go away, change the removal ordering in
ata_port_detach() so that the SCSI host is removed from the
port before ata_tport_delete() is called.

forever waiting for the write side to complete.

need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap

ASoC: pcm: Always honor DAI min and max sample rate constraints
snd_pcm_limit_hw_rates() will initialize the minimum and maximum sample rate for
the PCM stream based on the rates specified in the rates field. Since we call
snd_pcm_limit_hw_rates() after soc_pcm_init_runtime_hw() it will essentially
overwrite the min and max rate set in soc_pcm_init_runtime_hw(). This may cause
the minimum or maximum rate to be set to a value outside the range of one of the
components if one of the components sets either SNDRV_PCM_RATE_CONTINUOUS or
SNDRV_PCM_RATE_KNOT and the other component specified a discrete rate via
SNDRV_PCM_RATE_[0-9]* that is outside of the first component's rate range. To
fix this first calculate the minimum and maximum rates using
snd_pcm_limit_hw_rates() and then on top of that apply the contraints specified
in the snd_soc_pcm_stream structs.

ALSA: hda - Create Headhpone Mic Jack Mode when really needed
When a headphone jack is configurable as input, the generic parser
tries to make it retaskable as Headphone Mic. The switching can be
done smoothly if Capture Source control exists (i.e. there is another
input source). Or when user explicitly enables the creation of jack
mode controls, "Headhpone Mic Jack Mode" will be created accordingly.
However, if the headphone mic is the only input source, we have to
create "Headphone Mic Jack Mode" control because there is no capture
source selection. Otherwise, the generic parser assumes that the
input is constantly enabled, thus the headphone is permanently set
as input. This situation happens on the old MacBook Airs where no
input is supported properly, for example.
This patch fixes the problem: now "Headphone Mic Jack Mode" is created
when such an input selection isn't possible.

gpio: pl061: move irqdomain initialization
The PL061 driver had the irqdomain initialization in an unfortunate
place: when used with device tree (and thus passing the base IRQ
0) the driver would work, as this registers an irqdomain and waits
for mappings to be done dynamically as the devices request their
IRQs, whereas when booting using platform data the irqdomain core
would attempt to allocate IRQ descriptors dynamically (which works
fine) but also to associate the irq_domain_associate_many() on all
IRQs, which in turn will call the mapping function which at this
point will try to set the type of the IRQ and then tries to acquire

This moves the irqdomain initialization to a point where the spinlock
and GPIO chip are both fully propulated, so the callbacks can be used
without crashes.
I had some problem reproducing the crash, as the devm_kzalloc():ed
zeroed memory would seemingly mask the spinlock as something OK,
but by poisoning the lock like this:
u32 *dum;
dum = (u32 *) &chip->lock;
*dum = 0xaaaaaaaaU;
I could reproduce, fix and test the patch.

ftrace: Fix function graph with loading of modules
Commit
8c4f3c3fa9681 "ftrace: Check module functions being traced on reload"
fixed module loading and unloading with respect to function tracing, but
it missed the function graph tracer. If you perform the following
# cd /sys/kernel/debug/tracing
# echo function_graph > current_tracer
# modprobe nfsd
# echo nop > current_tracer
You'll get the following oops message:

The above mentioned commit didn't go far enough. Well, it covered the
function tracer by adding checks in __register_ftrace_function(). The
problem is that the function graph tracer circumvents that (for a slight
efficiency gain when function graph trace is running with a function
tracer. The gain was not worth this).
The problem came with ftrace_startup() which should always be called after
__register_ftrace_function(), if you want this bug to be completely fixed.
Anyway, this solution moves __register_ftrace_function() inside of
ftrace_startup() and removes the need to call them both.

to check for NULL and if it is, it will assign "(null)" to it instead
(similar to what glibc printf does).

ARM: vexpress/TC2: Implement MCPM power_down_finish()
This patch implements the power_down_finish() method for TC2, to
enable the kernel to confirm when CPUs are safely powered down.
The information required for determining when a CPU is parked
cannot be obtained from any single place, so a few sources of
information must be combined:
* mcpm_cpu_power_down() must be pending for the CPU, so that we
don't get confused by false STANDBYWFI positives arising from
CPUidle. This is detected by waiting for the tc2_pm use count
for the target CPU to reach 0.
* Either the SPC must report that the CPU has asserted
STANDBYWFI, or the TC2 tile's reset control logic must be
holding the CPU in reset.
Just checking for STANDBYWFI is not sufficient, because this
signal is not latched when the the cluster is clamped off and
powered down: the relevant status bits just drop to zero. This
means that STANDBYWFI status cannot be used for reliable
detection of the last CPU in a cluster reaching WFI.
This patch is required in order for kexec to work with MCPM on TC2.
MCPM code was changed in commit
0de0d6467525 ('ARM: 7848/1: mcpm:
Implement cpu_kill() to synchronise on powerdown'), and since then it
will hit a WARN_ON_ONCE() due to power_down_finish not being implemented

Jonathan writes:
First round of fixes for IIO in the 3.13 cycle.
The usual mixed bag of fixes.
* 3 cases where kconfig dependencies were missing. We need to keep a closer
eye on this in new drivers.
* hid_sensors was abusing the iio_dev->trigger pointer. We had a round
of clearing this out some time ago but this driver clearly slipped through.
* A misuse of the IIO_ST macro, in mcp3422, which we should really make a
concertive effort to finish removing.
* Avoid a double free introduced by recent buffer reference counting in the
one driver that (quite reasonably!) does things differently (am335x)
* A missing mutex_unlock in kxsd9 that means that driver has been non
functional for some time and no one noticed (including me who for once
actually has one of the supported devices).
* An incorrect assumption about the parameters of sign_extend32 in mcp3422.
So nothing controversial. The only substantial patch is the hid_sensors
one and that is actually just adding a new pointer to the devices private
state then moving the code over to it.
