are now filled in by the usb-serial core during driver registration,

This patch (as1550) fixes a bug in the usb-serial core that affects
the ftdi_sio driver and most likely others as well.  The core
implements suspend and resume routines, but it doesn't store pointers
to those routines in the usb_driver structures that it registers,
even though it does set those drivers' supports_autosuspend flag.  The
end result is that when one of these devices is autosuspended, we try
to call through a NULL pointer.

The patch fixes the problem by setting the suspend and resume method
pointers to the appropriate routines in the USB serial core, along
with the supports_autosuspend field, in each driver as it is
registered.

This pull request contains one workaround for a Silicon
Issue found on all RTL releases prior to 2.20a, which
would cause a metastability state on Run/Stop bit.

We also have some patches implementing a few extra Standard
requests introduced by USB3 spec (Set SEL and Set Isoch Delay),
as well as one patch, which has been pending for a long time,
implementing LPM support.

Last, but not least, we are splitting the host address space
out of the dwc3 core driver otherwise xHCI won't be able to
request_mem_region() its own address space. This patch is
only needed because we are (as we should) re-using the xHCI
driver, which is a completely separate module.

Together with these three big changes, come a few extra preparatory
patches which most move code around, define macros and so on, as
well as a fix for Isochronous transfers which hasn't been triggered
before.

This pull request is quite big, but mainly because there's a
giant rework of the s3c_hsotg.c driver to make it friendlier
for other users. Samsung Exynos platforms use the DesignWare
Core USB2 IP from Synopsys so it's a bit unfair to have the
driver work for Samsung platforms only. In short, the big
rework is in preparation to make the driver more reusable.

Another big rework in this pull request came from Ido, where
he's removing the redundant pointer for the endpoint descriptor
from the controller driver's own endpoint representation. The
same pointer is available through the generic struct usb_ep
structure.

Also on this pull request is the conversion of a few extra
controller drivers to the new style registration, which allows
multiple controllers to be available on the same platform and
helps remove global pointers from those drivers.

Together with those big changes, there's the usual fixes and cleanups
to gadget drivers. Nothing major.

TTY: pdc_cons, fix regression in close

The test in pdc_console_tty_close '!tty->count' was always wrong
because tty->count is decremented after tty->ops->close is called and
thus can never be zero. Hence the 'then' branch was never executed and
the timer never deleted.

This did not matter until commit 5dd5bc40f3b6 ("TTY: pdc_cons, use
tty_port").  There we needed to set TTY in tty_port to NULL, but this
never happened due to the bug above.

So change the test to really trigger at the last close by changing the
condition to 'tty->count == 1'.

Well, the driver should not touch tty->count at all.  It should use
tty_port->count and count open count there itself.

init: don't try mounting device as nfs root unless type fully matches

Currently, we'll try mounting any device who's major device number is
UNNAMED_MAJOR as NFS root.  This would happen for non-NFS devices as
well (such as 9p devices) but it wouldn't cause any issues since
mounting the device as NFS would fail quickly and the code proceeded to
doing the proper mount:

       [  101.522716] VFS: Unable to mount root fs via NFS, trying floppy.
       [  101.534499] VFS: Mounted root (9p filesystem) on device 0:18.

Commit 6829a048102a ("NFS: Retry mounting NFSROOT") introduced retries
when mounting NFS root, which means that now we don't immediately fail
and instead it takes an additional 90+ seconds until we stop retrying,
which has revealed the issue this patch fixes.

This meant that it would take an additional 90 seconds to boot when
we're not using a device type which gets detected in order before NFS.

This patch modifies the NFS type check to require device type to be
'Root_NFS' instead of requiring the device to have an UNNAMED_MAJOR
major.  This makes boot process cleaner since we now won't go through
the NFS mounting code at all when the device isn't an NFS root
("/dev/nfs").

ACPI: Fix D3hot v D3cold confusion

Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot
in some places, but D3cold in other places.

After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD;
and all references to D3hot use ACPI_STATE_D3_HOT.

ACPI's _PR3 method is used to enter both D3hot and D3cold states.
What distinguishes D3hot from D3cold is the presence _PR3
(Power Resources for D3hot)  If these resources are all ON,
then the state is D3hot.  If _PR3 is not present,
or all _PR0 resources for the devices are OFF,
then the state is D3cold.

This patch applies after Linux-3.4-rc1.
A future syntax cleanup may remove ACPI_STATE_D3
to emphasize that it always means ACPI_STATE_D3_COLD.

12 years agoseqlock: add 'raw_seqcount_begin()' function
Linus Torvalds [Fri, 4 May 2012 22:13:54 +0000 (15:13 -0700)]
seqlock: add 'raw_seqcount_begin()' function

The normal read_seqcount_begin() function will wait for any current
writers to exit their critical region by looping until the sequence
count is even.

That "wait for sequence count to stabilize" is the right thing to do if
the read-locker will just retry the whole operation on contention: no
point in doing a potentially expensive reader sequence if we know at the
beginning that we'll just end up re-doing it all.

HOWEVER.  Some users don't actually retry the operation, but instead
will abort and do the operation with proper locking.  So the sequence
count case may be the optimistic quick case, but in the presense of
writers you may want to do full locking in order to guarantee forward
progress.  The prime example of this would be the RCU name lookup.

And in that case, you may well be better off without the "retry early",
and are in a rush to instead get to the failure handling.  Thus this
"raw" interface that just returns the sequence number without testing it
- it just forces the low bit to zero so that read_seqcount_retry() will
always fail such a "active concurrent writer" scenario.

Linus Torvalds [Fri, 4 May 2012 21:46:02 +0000 (14:46 -0700)]
Fix __read_seqcount_begin() to use ACCESS_ONCE for sequence value read

We really need to use a ACCESS_ONCE() on the sequence value read in
__read_seqcount_begin(), because otherwise the compiler might end up
reloading the value in between the test and the return of it.  As a
result, it might end up returning an odd value (which means that a write
is in progress).

If the reader is then fast enough that that odd value is still the
current one when the read_seqcount_retry() is done, we might end up with
a "successful" read sequence, even despite the concurrent write being
active.

In practice this probably never really happens - there just isn't
anything else going on around the read of the sequence count, and the
common case is that we end up having a read barrier immediately
afterwards.

So the code sequence in which gcc might decide to reaload from memory is
small, and there's no reason to believe it would ever actually do the
reload.  But if the compiler ever were to decide to do so, it would be
incredibly annoying to debug.  Let's just make sure.

12 years agousb: gadget: composite: prevent a memory leak when configuration bind fails
Yongsul Oh [Tue, 20 Mar 2012 01:38:38 +0000 (10:38 +0900)]
usb: gadget: composite: prevent a memory leak when configuration bind fails

In some USB composite gadget drivers, the configuration's bind function called
by the usb_add_config() calls multiple bind config functions. (for example cdc2
configuration bind function in the cdc_do_config() of the cdc2.c has two
functionality bind config functions.
  - the ecm_bind_config() & the acm_bind_config())

In each functionality bind config function, new instance is allocated and
finally added by the usb_add_function().

So if an error occurred during the second functionality bind config (for
example an error occurred at the acm_bind_config() after succeeding of the
ecm_bind_function()), the instance created by the acm_bind_config() cannot be
freed creating a memory leak.

This patch fixes this issue.

ep->desc is set to NULL on endpoint disable. That means once an endpoint

first disable endpoints to make sure I have no requests on the fly and
then free frequests. On dummy I am leaking memory here.
Since I can't imagine a reason why it should be a bad thing, lets allow
to free requests on disabled endpoints. On removal of composite the ep0
request is removed so lets allow that here as well.
