ath10k: remove unnecessary htt rx corruption check

While fixing a bug reported by Avery I went ahead
and added a warning suspecting there might be
something more to the bug. This ended up with
people reporting they see warnings during heavy
traffic. This bought me some time and helped me
understand the problem better - apparently fw/hw
can report a chained msdus as follows: 1 msdu, 1
chained, 1 msdu (0 length).

The patch removes the extra check but leaves the
other change that fixed the original skb_push
panic bug (msdu_chaining was overwritten in an
unfortunate way which made the above example to
be treated as non-chained case).

ath10k: fix 8th virtual AP interface with DFS

Firmware 10.x supports up to 8 virtual AP interfaces, but in a DFS
channel it was possible to create only 7 interfaces as ath10k internal
creates a monitor interface for DFS. Previous vdev map initialization
was missing enough space for 8 + 1 vdevs due to wrong define used and
that's why there was no space for 8th interface. Use the correct define
TARGET_10X_NUM_VDEVS with 10.x firmware to make it possible to create
the 8th virtual interface.

HID: sensor-hub: make dyn_callback_lock IRQ-safe

dyn_callback_lock is being taken from IRQ context through hid_irq_in() ->
hid_input_report() -> sensor_hub_raw_event() -> sensor_hub_get_callback(),
therefore anyone else acquiring it needs to disable IRQs to disable deadlocks.

ARM: OMAP2+: hwmod: Change hardreset soc_ops for AM43XX

am43xx reset register layout is more similar to am33xx than omap4 so
use the am33xx functions for hwmod hardreset soc_ops rather than the
currently used omap4 functions. Without this, assert_hardreset and
deassert_hardreset will not work on am43xx.

ext4: Fix buffer double free in ext4_alloc_branch()

Error recovery in ext4_alloc_branch() calls ext4_forget() even for
buffer corresponding to indirect block it did not allocate. This leads
to brelse() being called twice for that buffer (once from ext4_forget()
and once from cleanup in ext4_ind_map_blocks()) leading to buffer use
count misaccounting. Eventually (but often much later because there
are other users of the buffer) we will see messages like:
VFS: brelse: Trying to free free buffer

Another manifestation of this problem is an error:
JBD2 unexpected failure: jbd2_journal_revoke: !buffer_revoked(bh);
inconsistent data on disk

The fix is easy - don't forget buffer we did not allocate. Also add an
explanatory comment because the indexing at ext4_alloc_branch() is
somewhat subtle.

ARM: dts: Enable twl4030 off-idle configuration for selected omaps

N900 now seems to shut down the external oscillator when hitting
off-idle.

And Beagle XM seems to have OSC_EN pin connected to allow shutting
down the oscillator looking at the schematics. The oscillator
output is cut off in off-idle and you can monitor it from R56 on
the bottom side of the board near the power jack. Note that for
beagle we need to also enable the UART wake-up event, the others
have that enabled in earlier patches.

OMAP37XX EVM (TMDSEVM3730) does not seem to have twl4030 clken
pin connected, so there is no point trying to enable shutting
down of the oscillator on it for the extra latency it adds.

Merge tag 'for-v3.16-rc/omap-fixes-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.16/fixes

Two OMAP hwmod patches for early v3.16-rc kernels.

There's one OMAP SoC integration fix for the AM43xx SoC, without
which, IP blocks can't be placed into hard-reset.

There is also one OMAP5 SoC data addition patch that should have gone
in for v3.16. Normally I wouldn't send this as part of an -rc series,
since it's not technically a fix. But I'd like to make an exception in
this case because:

- it's intended to go in very early in the v3.16-rc series (or even
pre-rc1);

- it's a fairly small change;

- the impact is limited to a single SoC and a single device;

- the only reason that it didn't go in earlier is because it "slipped
through the cracks," rather than for any technical reason.

Basic build, boot, and PM test logs are available here:
