msm: cpufreq: make the gov stop part fully atomic

In the function cpufreq_governor_dbs, the case CPUFREQ_GOV_STOP
is not completely atomic. The removal of sysfs is outside the
critical path. If a START/STOP done frequently from user space
then there is chance of adding the sysfs interface before removal.
This creates a warning from sysfs saying creating an already
existing entry.

Also once it fails to create, cpufreq_governor_dbs returns with
error code. The dbs_enable value is incremented which is not
rolled back and cpufreq core tries to set the old
governor. This might create further problems.

Hence the removal of sysfs entry should happen in the critical
path.

ASoC: WCD9310: Defer the setup of headphone removal detection.

After the inserted accessory is detected as a valid headphone,
polling is performed on the microphone to correct the accessory
detection in case it was wrongly identified as a headphone.

It was observed that at the end of polling, headphone removal
interrupt was fired, causing headphone playback to stop. Fixed
by deferring the headphone removal setup until either polling is
complete or polling detects a removal

ASoC: wcd9310: reduce mbhc button release GPIO debounce time.

Current GPIO debounce time is too long so it delays next button
press detection.  Reduce this debounce time so driver can detect
next button press and release quickly.
Typically mic voltage ramps up within few milliseconds after button
release so 50ms is long enough.

ASoC: wcd9310: Enhance OCP reporting logic.

CODEC has over current protection(OCP) finite state
machine for both left and right headphone while CODEC
driver tries to delay reporting of OCP event after
CODEC reporting OCP two times. Current CODEC driver
implementation results in unlocking one of headphone
power amplifier when OCP reported on both headphone.
Change the behavior to report OCP event for a give
headphone immediately if OCP already occurs on opposite
headphone.

ASoC: wcd9310: Resend edge triggered GPIO IRQ

If MBHC GPIO IRQ for mechanical headset detection asserted while power
management's suspend call chain is being called, wcd9xxx_lock_sleep will
fail to wait for system's resume since power management interface has
to finish suspend in order to resume system.
In this case, interrupt cannot be handled as codec driver cannot
guarantee if underlying bus is awake.
Wake up system and resend the IRQ for this situation.

msm: kgsl: Don't wake up gpu on kgsl_ioctl calls if not necessary

This is Iee3db5401bdad1808a09d104e0daecfc3716cbb4 change ported
manually from the msm-3.4/msm-3.7 branch to the jb_2.5 branch.

The current code wakes up gpu on all kgsl_ioctl() calls that need
to hold device->mutex. However there are some kgsl_ioctl() calls that
don't need that. That fix introduces a bit of info to mark such
functions, and don't wake up gpu calling them to save some power.
