This is a note to let you know that I've just added the patch titled
Revert "[media] videobuf2-v4l2: Verify planes array in buffer dequeueing"to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...
The filename of the patch is: revert-videobuf2-v4l2-verify-planes-array-in-buffer-dequeueing.patch and it can be found in the queue-4.4 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

commit 93f0750dcdaed083d6209b01e952e98ca730db66 upstream.
This patch has been already applied to the 4.4-stable tree --- and the original has been re-applied as well, just as in upstream.
The original revert was done because another patch was missing the tree (commit 93f0750dcdaed083d6209b01e952e98ca730db66 upstream), not because there was a problem with the patch itself.
In other words, this patch must be dropped.
Really?
This is a mess. I see the following commits in the stable 4.4 tree:
In the 4.4.9 release the following upstream commit was backported: 2c1f6951a8a8 ("[media] videobuf2-v4l2: Verify planes array in buffer dequeueing")
then in 4.4.11 it was reverted by backporting: 93f0750dcdae ("Revert "[media] videobuf2-v4l2: Verify planes array in buffer dequeueing"")
Then finally, in 4.4.19 this commit gets added: 83934b75c368 ("[media] videobuf2-v4l2: Verify planes array in buffer dequeueing")
So, is 83934b75c368 ok to backport, but 2c1f6951a8a8 was not?
Because they look identical to me...
So, what am I missing here?
thanks,
