msm: kgsl: Re-run the events handler when inflight goes to zero

The event code is sensitive to race conditions with the GPU. We just
can't spend all day the event loops waiting for timestamp to expire.
The dispatcher loop on the other hand is far less sensitive to the
race with the GPU so we have a very good idea when the GPU is idle.

When inflight goes to zero re-run re-queue the event handler to catch
any stragglers.

bluetooth: unlock spin on bluesleep_stop before controling the hsuart power

Kernel migh be in sleep to wait for rpm communication when it controls the
hsuart power. So should unlock the spin before controling the hsuart
power.

msm_serial_hs: Fix the unbalanced clk_count

If clock vote is failed, clk_count is added. It may cause the unbalanced
clk_count. Also it's possible to be nagative clk_count on unvote. So do
not decrease the clk_count if it's already zero.

msm_serial_hs: check the returned value of clock vote

If voting clock is failed, we should not access the registers.
It may cause a crash to access the unclocked register.

msm_serial_hs: Fix race condition with BAM rx pipe

Crash observed due to the race condition with bam
rx pipe during sps_disconnect and sps_transfer_one
operations executed at the same time on two CPUs.

Because of this race condition rx bam descriptor
pointer becomes NULL and accessing of this pointer
leads to crash.

This patch waits for sps_transfer_one function to
complete, if it is in progress, before calling
sps_disconnect function from the set_termios.

msm: mdss: unmap user writeback buffers after session is terminated

Currently if buffers are provided to writeback driver through user space
ioctl, these are never unmapped and may cause leaks in memory. Also, we
can reuse the nodes which are already mapped until session is
terminated.

msm: mdss: allow re-queue of writeback buffers

When a buffer has been properly processed, user space may choose to use
sync fence to acknowledge when buffer is complete. In such cases dequeue
is not not necessary, allow this use case by allowing client to re-queue
of writeback buffers as long as the buffer has been properly processed
already.

msm8974_pwm_vibrator: rework for vibration start/stop

To be flexible, we use the delayed workqueue instead of usleep.
And the driver already support for vibrator stop. So We don't need to stop
it repeatedly. We need a force stop only when upperlayer send a stop signal
during vibing.
