probe function parses device tree at the begginning. device tree should not
be reparsed in the middle of the probe.  use the first parse value.

mmc: sdhci-msm: fix issue with tuning command

As of now we ignore CRC/INDEX command failures to tuning command
and still wait for data from card but in case the card did not
receive the command, it won't send the data. This is causing
software request timeout for tuning commands. Hence, software
must not ignore such cmd errors for tuning commands but end the
request immediately after resetting the controller for both CMD
and DATA. Also, wait for 146 MCLK cycles for card to send out the
data and thus to move to transfer state. Its corresponding phase must
also be considered as bad phase.

msm: vidc: Add NULL pointer check before deiniting controls

Add NULL pointer check in deinit function, and return -EINVAL
when NULL pointer is found.
Without this change, accidentally, msm_venc_ctrl_deinit() will be called
with a null pointer parameter, which will cause kernel panic.

msm: vidc: Fix race condition during concurrent sessions

The core->instances list structure is guarded by
mutex core->lock, whenever a new video instance is added
or deleted from the list. However this list was accessed
from certain functions without acquiring the lock, which
resulted in race condition, causing the device to crash.
Also clean up the core locking mechanism.

msm: vidc: Expose extradata size to userspace

Previously, the extradata size was included within VENUS_BUFFER_SIZE
and callers (primarily in userspace) wouldn't know how much extra
padding was added to the buffer size. Exposing it allows userspace to
query directly instead of doing guesswork.
