msm: kgsl: Properly record the size of the sglist in the memdesc

It was possible to fail out of kgsl_sharedmem_alloc after a sglist was
allocated but before we saved the size of the allocation which caused
problems when the sglist was freed during cleanup.

ASoC: wcd9xxx: Fix MBHC irq handler deadlock scenario.

There is a chance to encounter deadlock when either electrical mbhc irq
or mechanical mbhc irq releases resource lock to let polling thread finish
its job.  This is due to the possibility of one irq handler can preempt
already running the other type of irq handler.
Introduce a new mutex to avoid this preemption.

msm8930: Use appropriate VDD_CP for msm8930 platform

The VDD_CP supply to WCD9304 codec is supplied from PMIC voltage
regulator S4. WCD9304 codec expects VDD_CP of either 1.8 volts or
2.2 volts. Since PM8038 can supply VDD_CP of upto 2.2 volts whereas
PM8917 can suuply VDD_CP of only 1.8 volts, dynamically select the
voltage regulator request value from platform data by fixing up
the platform data during bootup.

usb: gadget: u_data_hsic: Use GFP_KERNEL where ever possible

The USB requests are allocated using dma pool API.  The dma pool has
limited memory for non-sleeping use case.  The current code does not
free USB requests during subsystem restart.  The requests are freed
only after cable is disconnected.  If subsystem restart happens
multiple  times without disconnecting cable, system may run out of the
dma pool memory.  This is leading to URB submission failures.  Use
GFP_KERNEL where ever possible.

msm: display: Fix composition issues when framework rebooted in suspend.

Currently, if framework is rebooted while in suspend mode, borderfill
is not unset due to which MDP composition can not be enabled. This patch
fixes the issue.

msm_fb: display: add one more pipe_commit delay before free ion buffer

It is possible that two consective pipe_commits happen within
same vsync period.  This will cause iommu page fault due to an ion buffer
that is being fetched by mdp's pipe is freed. It needs one pipe_commit
delay to free ion buffer to prevent iommu page from happening. Therefore
an extra free stage is needed to empty ion buffer free list.
Also, ION_IOMMU_UNMAP_DELAYED flag is not necessary at mapping of an
ion buffer since one pipe_commit delay had been added.

msm_fb: display: fix the suspend/resume hang caused by wait4vsync stuck

wait_for_completion in wait4vsync stucks after multiple suspend/resume
tests. The cause is that when show_event timeout happens, or vsync isr
is disabled for long time, wait_vsync_cnt resets to zero, and in vsync
isr complete_all has no chance to be called which caused mdp hang. So
complete_all needs to be called whenever show_event has timeouts.

rmnet_smux: device state check condition removed

If SSR happens in high watermark hit case, then the high-watermark-hit
condition is not reset correctly which causes TX data stall after
recovered from SSR.

In the SSR case, SMUX sends disconnect event to clients. For this event,
the RMNET client changes the device state to INACTIVE which prevents
call to msm_smux_close() from smux_rmnet_remove().

Remove the device state check condtion to iopen and close the RMNET
logical channel during RMNET device probe and remove.
