[PATCH 7/7] media: venus: Set buffer to FW based on FW min count requirement.
From: Dikshita Agarwal
Date: Wed May 19 2021 - 05:38:26 EST
- Get the min buffer count required by FW from source event change
and use the same value to decide actual buffer count and for
buffer size calculation.
- Setup DPB and OPB buffers after session continue incase of
reconfig.
