06efbeb4a4 hp_accel: fix race in device removal
The work queue has to be flushed after the device has been made
inaccessible.  The patch closes a window during which a work queue might
remain active after the device is removed and would then lead to ACPI
calls with undefined behavior.

009a891b22 mmc: atmel-mci: prevent kernel oops while removing card
The removing of an SD card in certain circumstances can lead to a kernel
oops if we do not make sure that the "data" field of the host structure is
valid.  This patch adds a test in atmci_dma_cleanup() function and also
calls atmci_stop_dma() before throwing away the reference to data.

1c6fe0364f cpuidle: Fix incorrect optimization
commit 672917dcc7 ("cpuidle: menu governor: reduce latency on exit")
added an optimization, where the analysis on the past idle period moved
from the end of idle, to the beginning of the new idle.

Unfortunately, this optimization had a bug where it zeroed one key
variable for new use, that is needed for the analysis.  The fix is
simple, zero the variable after doing the work from the previous idle.

During the audit of the code that found this issue, another issue was
also found; the ->measured_us data structure member is never set, a
local variable is always used instead.

fde4e2f732 HID: fix suspend crash by moving initializations earlier
Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.

This patch (as1378) fixes the bug by moving the initialization
statements up into usbhid_probe().

Avoid that by waiting for the firmware loading to finish
(whether successfully or not) before the unbind in
ar9170_usb_disconnect.

1176568de7 md: restore ability of spare drives to spin down.
Some time ago we stopped the clean/active metadata updates
from being written to a 'spare' device in most cases so that
it could spin down and say spun down.  Device failure/removal
etc are still recorded on spares.

However commit 51d5668cb2 broke this 50% of the time,
depending on whether the event count is even or odd.
The change log entry said:

   This means that the alignment between 'odd/even' and
    'clean/dirty' might take a little longer to attain,

how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.

So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately.  There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update).  We just piggy-back on that.

03b1930efd V4L/DVB: saa7146: fix regression of the av7110/budget-av driver
An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.

Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.

The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.

6a4f0623a4 V4L/DVB: V4L - vpfe capture - fix for kernel crash
As part of upstream merge, set_params() function was removed from isif.c.
This requires removal of BUG_ON() and check for set_params ptr in
vpfe_capture.c. Without this kernel crash dump is seen while bootup on DM365

Also made following changes:-

 1) converted error messages to debug messages since it is not right to flood
    the console with error messages for user mistakes.
 2) returns -EINVAL if ioctl is not supported

The 046d:08da usb id shouldn't be associated with the stv06xx driver as they're
not compatible with each other.
This fixes a bug where Quickcam Messenger cams fail to use its proper driver
(gspca-zc3xx), rendering the camera inoperable.

xawtv using DGA on a Radeon graphics card provides bogus

6ec82562ff veth: Dont kfree_skb() after dev_forward_skb()
In case of congestion, netif_rx() frees the skb, so we must assume
dev_forward_skb() also consume skb.

Bug introduced by commit 445409602c
(veth: move loopback logic to common location)

We must change dev_forward_skb() to always consume skb, and veth to not
double free it.
