Buffers can be queued to driver before the planes are
set to start streaming. Queue those buffers to firmware
once start streaming is called on both the planes.

yes and this is done in venus_helper_m2m_device_run mem2mem operation
when streamon on both queues is called, thus below function just
duplicates .device_run.
Do you fix an issue with that patch?

Hi Stan,
As I considered playback sequence as well, this function
"venus_helper_m2m_device_run" was muted as a part of it. So I had to
explicitly implement this function for encoder.
For now, we can omit this patch. Once the playback sequence gets merged
into upstream, we can re-look into this.

Sorry, I didn't look deeply into playback sequence patches yet, but
looks like we have to fix them first. So please drop this patch.
