ENGR00285273-3 IPU dev:Remove unnecessary memset before kfree
This patch removes unnecessary memset() before kfree().
Also, it fixes a potential NULL pointer dereference(writing
to a freed block of memory).
ENGR00290361-1 IPUv3 IC:Add check for a IDMAC errata
The IPUv3 IDMAC has a bug to read 32bpp pixels from a
graphics plane whose alpha component is at the most
significant 8 bits. The bug only impacts on cases in which
the relevant separate alpha channel is enabled.
This patch adds check for the errata so that the bad
cases won't be triggered.
