Flash LED tps61310: use alloc_workqueue() instead of create_workqueue()

MSM8930 uses tps61310 in which work_queue was getting created
each time flash is turned ON. So using alloc_workqueue().

diag: Reduce error message frequency

Some diag error messages are printed with high frequency. This
cause flooding of kernel logs. Rate limiting these messages will
help reading kernel logs.

msm: ipc: Possible memory corruption due to Sign Conversion

msm_ipc_router_skb_to_buf() takes an unsigned argument and assigns the
same to a signed local variable. This might cause issues when the value
of the argument is too high.

Change the datatype of the local variable to unsigned.

msm: kgsl: Change an overflow check to be "smart" compiler proof

In its infinite wisdom, GCC will optimize out this overflow check:

   if ((gpuaddr + size) < gpuaddr)

Which might totally make sense for the compiler but it doesn't do us
a bit of good. Replace the existing overflow check with something
that GCC can't ignore.

Rotator getting stuck leading to fence timeout

Even though cancel_delayed_work should cancel the worker thread
in some race condition it can fail and get scheduled.
To avoid this situation use cancel_delayed_work_sync.
Also rotator_lock mutex need not be unlocked while waiting for isr
as isr does not aquire this mutex for doing its operations.
It is after this unlock of mutex sometimes in race condition rotator
clock is getting disabled via the msm_rotator_rot_clk_work_f
