Subject: Request patch to -stable 4.4+ "media: v4l2-mem2mem: always consider OUTPUT queue during poll"
Date: Thu, 12 Aug 2021 19:58:22 +0800	[thread overview]
Message-ID: <20210812115822.5411-1-lecopzer.chen@mediatek.com> (raw)

Hi Greg

Reason:

We found without this, Poll() infinitely wait because OUTPUT queue
will never signaled after last CAPTURE queue is de-queued.
And some buffer can't be popped as expected.


commit id: 566463afdbc43c7744c5a1b89250fc808df03833
subject: "media: v4l2-mem2mem: always consider OUTPUT queue during poll"

This should be applied to 4.4+ without conflict after 
(f1a81afc98e315f4bf600d28f8a19a5655f7cfe0 "[media] m2m: fix bad unlock balance")


Thanks,
Lecopzer
