The commit description is misleading, looks like you're doing functional
changes, but you're just changing loglevels... and the title is also a
little confusing, so.. I would propose:

media: mediatek: vcodec: Avoid unneeded error logging

Since the LAT decoder works faster than its CORE, getting the trans buffer may
be done only after CORE finishes processing: avoid printing an error if the
decode function returns -EAGAIN, as this means that the buffer from CORE is not
yet available, but will be at a later time.

Also change the log level for calls to vdec_msg_queue_dqbuf() in H264 and VP9
LAT decoder drivers to avoid excessive logging.

Cheers,
Angelo
