Hi All,
This patch set uses the vb2 ops helpers for wait_prepare and
wait_finish callbacks for drivers which using vb2 helpers.
This patchset is compile tested only.
I am not sure on how mem2mem drivers work because the have
2 queues sharing the same lock, so not sure if these
changes to mem2mem drivers are valid.

So I'm not convinced that this patch improves things; it moves a tiny bit
of code into another file where anybody reading the driver will have to
go look to see what's going on. But I guess it doesn't really make
things worse either; I won't try to stand in its way. It would be nice
to see a real changelog on the patch, though.

Sorry there is no movement of code to other file. And I dont see any
reason why anybody reading will go haywire its a standard v4l2 thing.
The subject explains it all, If you still want me to elaborate I can
post a v2.

Whatever, I said I wouldn't stand in the way.

Here I totally disagree, though. You say what you are doing, not why.
What's strange about the idea that a patch should have a reasonable
changelog?

Hi,
Please provide a commit description. No matter how obvious the commit
seems.
