[PATCH v2,1/4] media: mediatek: vcodec: Avoid unneeded error logging

From: Yunfei Dong
Date: Mon Apr 17 2023 - 08:32:24 EST


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.
