It's next to impossible to review just large diffs, but it is unavoidable for
changes like this I guess.
I do recommend that you do a 'git grep videobuf2-core' to make sure all usages
of that have been replaced with videobuf2-v4l2. I think I saw videobuf2-core
mentioned in a comment, but it is hard to be sure.
It would also be easier to review if the renaming of core.[ch] to v4l2.[ch] was
done in a separate patch. If it is relatively easy to split it up like that,
then I would appreciate it, but if it takes a lot of time, then leave it as is.
Anyway, assuming that 'git grep videobuf2-core' doesn't find anything:
