msm: audio: qdsp6v2:  Check return code from audio_aio_open()

When audio_aio_open() is triggered in blocking fashion, it  frees audio
resouces and returns error code. In the current implementation,  callers
did not check the error code which can lead to dereference to freed
resources and cause system crash.  Update the callers to check return
code and then return error back to application to avoid the issue. In
the meanwhile, update the audio_aio_open not to free memory for caller
and leave the caller to free the memory in error condition.

media: dvb: mpq: Limit number of TS packets on secure demux input

Limit number of TS packets available to secure demux for processing
in any single processing session. This is done in order to prevent
large input buffer that require a long processing time and may cause
latency and overflow situations.
The limit can be fine-tuned as it is a module parameter.

msm_fb: display: provision of mixer reset function

Mdp has hardware bug which cause fetch engine stalled if less than
3 pixels at begin or end of line be cropped into destination. Reset
mixer can fix this problem. However frame work can provide better
work around solution by falling back to gpu if the condition detected.
This patch will not reset mixer but provide mixer reset function in
case of mixer reset is need in future.

power: pm8921-charger: Do not update "type" property of usb_psy

The userspace fails to detect the supply type as USB if "type"
property of usb_psy power-supply class is set to anything other
than USB at init. The driver ends up setting this to type
-UNKNOWN at bootup if there is no USB source present
-USB_DCP/ACA if a wall charger is present
This causes issues with displaying the charger source later on
since the USB path is not noted by the userspace. Moreover, the
userspace ignores the changes to the type property at runtime
making it futile for the driver to update it.

Use local driver data to store the usb type information
and use this to determine the supply-type. Keep the
usb_psy.type set to USB always.

gpu: ion: suppress excessive logging for expected failure cases

We expect alloc_pages to fail for high-order pages under stressed
memory conditions. It should then fall back to lower-order page
allocations but due to excessive logging the system crashes. Use
__GFP_NOWARN for high-order allocations to avoid excessive logging.
