Subject: media: s5p-mfc: Set context for valid case before calling try_run
Author: Aakarsh Jain <aakarsh.j...@samsung.com>
Date: Wed Dec 13 13:41:03 2023 +0530
Context bit is set for hardware execution if there is a buffer in
source and destination queue before calling try_run in the
init_buffers function. Now there will be a new context created and
hardware will be invoked for the buffer queued instead of waiting for
another buffer to be queued from userspace to set this context bit for
hw execution.
