msm: kgsl: Wake up gpu on kgsl_ioctl_timestamp_event only if necessary

Any call of kgsl_ioctl_timestamp_event wakes up gpu. In some cases
(like retired timestamp) it's not necessary. Wake up gpu only if it's
necessary.

ASoC:msm: Increase Proxy buffering

-Proxy buffering can overflow if BT
playback setup takes a lot of time
-Fix this by increasing the proxy
buffer size so that we will end
up buffering the additional data that
can come in during this time

diag: Command registration not happening properly

Some CM command registrations are not happening properly
on apps side. This could be because some smd events
for control type were getting missed. Make changes
in order to read pending SMD packets for control
type.

tty: n_smux: fix deadlock between RX and TX workers

smux_handle_rx_open_ack function acquires the channel state spin lock
and tries to add the channel into ready list causing spin lock lockup
between smux_rx_worker thread and smux_tx_worker thread running on
two different CPUs.

Add the channel to ready list after releasing the state spin lock.

msm: rotator: Wait for the pending commits in finish IOCTL

Due to asynchronuous rotator mechanism, sometimes the
MSM_ROTATOR_IOCTL_FINISH arrives before the previously queued
do_rotate work is completed. This causes fence to be signalled
before the buffer is used by rotator. In case of fast YUV 2 pass
scenario, this causes IOMMU page fault on 2 pass buffers, since
the buffer is unmapped when the rotator is still using it. Hence,
wait for the pending commit works to be finished before releasing
the fence and freeing the 2 pass buffers.

EHCI: HSIC: Disable CPU Idle states before resuming the port

The CPU idle states are disabled to reduce the USB GPT interrupt
latency during bus resume.  The pm_qos_update_request() is blocked
until all the online cores are brought out of idle states. If this
call is blocked for longer time than resume signaling, the resume
sequence is repeated again.  Fix it by calling pm_qos_update_request()
before resuming the port.

usb: u_bam: Fix spinlock leak followed by lockup from workqueue

Driver has missing code to release spinlock while returning from
workqueue in case of memory allocation failures.
Returning from workqueue without releasing spinlock messes up
with worker thread and kernel keeps throwing up warnings like:
"BUG: workqueue leaked lock or atomic: kworker/u" for any
sleeping function called from worker thread afterwards. Later
when driver again tries to acquire same (unreleased) spinlock
it results in spinlock lockup.

Bluetooth: Disable Sniff on HID ACL(s) if SCO is active

This patch disables sniff support on HID ACL(s) if SCO is active by
updating Link Policy settings. Once SCO is disabled, link policy is
again updated to re-enable Sniff on HID ACL(s). Without this patch
it was seen in presence of SCO, disconnection was observed on HID
ACL(s).

Bluetooth: Fix for the l2cap layer crashes while turning OFF BT

-This patch fix a case where while turning OFF BT l2cap channel
 & l2cap conn get deleted in one process context, which preempted
 the another process, where l2cap con was being used while trying to
 disconnect l2cap.  As the result l2cap conn pointer become invalid.
 Later which is leading a crash.  L2cap conn should be guarded by
 spin lock while disconnecting l2cap to avoid preemption which will
 avoid  crash due invalid conn pointer.

-This patch fix list_add crash due to invalid skb pointer.
 & BUG sleep warning as well.
