SoC: msm: qdsp6v2: return DEFER code when probe is not done

Probe may not be done when first alloc api is called. Need to return
DEFER error so that client can try later.

The acdb_mmap fuction does a size calculation but

numbers possible. Changing the variable to unsigned
ensures that the size used is never out of bounds.

Channel info data structure is parsed from userspace and if
user does not set the no. of channels correctly, it could lead
to security vulnerability if we don't check for overflow when the

to check for overflow during multiplication.

ALSA: core: Fix crash by avoiding appl_ptr crossing 32-bit boundary

Incase of A2DP usecase using proxy driver, appl_ptr has
boundary value as 0x60000000 frames in sw_params for stereo(2 channels).
When this value crosses 0x40000000, then userspace calculating
appl_ptr at bytes results in crossing 32-bit value 0x100000000,
and points to 0x0 offset which can result in crash or pop.
To avoid above scenario, set the sw_params appl_ptr boundary value
within 0x40000000. Added proper check at sw_params update
to set this value correctly within 32-bit boundary(frames).

ASoC: msm: Fix playback failure on device switch during ULL playback

When a device switch happens for ultra low latency playback, we are
opening a regular playback COPP. ULL stream is routed to a non ULL
COPP. ULL stream can be only routed to a ULL COPP. This results in
playback failures. The fix is to use the perf mode flag as a
part of front end instead of back end dai.
