[PATCH 6.19 156/844] media: chips-media: wave5: Process ready frames when CMD_STOP sent to Encoder

[Sasha Levin]

From: Brandon Brnich <b-brnich@xxxxxx>

[ Upstream commit 5da0380de41439ed64ed9a5218850db38544e315 ]

CMD_STOP being sent to encoder before last job is executed by device_run
can lead to an occasional dropped frame. Ensure that remaining ready
buffers are drained by making a call to v4l2_m2m_try_schedule.
