The first patch helps to improve the response time by reducing the
polling time of the tee command status variable.

Second patch is a bug fix to handle multi-threaded use-case.
During testing, race condition was seen due to missing synchronisation
in writes to the TEE ring buffer. This patch helps to resolve that.

v3:
 * Fixed checkpatch.pl warning

v2:
 * Updated copyright year as a part of code change

Rijo Thomas (2):
  crypto: ccp - reduce tee command status polling interval from 5ms to
    1ms
  crypto: ccp - fix command queuing to TEE ring buffer
