Subject: [PATCH v2 0/2] media: v4l2-mem2mem: fix poll() bug

Thanks to the feedback on the first version, this one removes even more code.

I have simplified patch 1/1 to just address the issue without moving code,
since this is easier to understand and needs to be done for 2/2 anyway. As a
consequence the code has changed a bit and I did not carry the Reviewed-by tags.

Changes from v1:

* Simplify patch 1/1,
* Remove unneeded checks for DONE or ERROR status,
* Rephrased comment about exiting early.

Alexandre Courbot (2):
  media: v4l2-mem2mem: always consider OUTPUT queue during poll
  media: v4l2-mem2mem: simplify poll logic
