I doubt you're going to get many comments on this patch, being so large
and spread across all drivers. I'm not going to bother trying to edit
this down to something more sensible, I'll just plonk my comment here.

For the mvpp2 driver, you're only updating a comment - and looking at
it, the comment no longer reflects the code. It doesn't make use of
tasklets at all. That makes the comment wrong whether or not it's
updated. So I suggest rather than doing a search and replace for
"tasklet" to "BH blahblah" (sorry, I don't remember what you replaced
it with) just get rid of that bit of the comment.

Thanks.
