All -
I've fixed most of the checkpatch warnings (save for LONG_LINE and
BIT_MACRO that we don't care so much about) while applying. It's not
something I normally do, and I really don't want to find these when the
series is at v7 and the same warnings have been there since September
and I keep being pinged about merging.
Keeping the driver nice and clean is your job too, not just mine.
BR,
Jani.
