Merge kernel.org:/pub/scm/linux/kernel/git/mchehab/v4l-dvb.git with fixups

This merges the DVB tree, but fixes up the history that had gotten
screwed up by a broken commit.

The history is fixed up by re-doing the commit properly (taking the
resolve from the final result of the original), and then cherry-picking
the commits that followed the broken merge.
