Re: [PATCH] media: s5p-mfc: set V4L2_BUF_FLAG_LAST flag on final buffer

[Hans Verkuil]

Hi all,

I'm going through a bunch of (very) old patches in my patchwork TODO list
that for one reason or another I never processed. This patch is one of
them.

I don't feel comfortable merging this, given the follow-ups that were posted.

If someone wants to get this in anyway, then please make a new patch. I'm
marking it as 'Changes Requested' in patchwork.

Regards,

	Hans
