Nicely done.
Couple of nitpicks:
- Please no double empty lines (removed some, added some ;-)
- still a couple of c99 comments
- (later or intro patch): dem_request_region() in probe could help
with cleanup, you could use the devm_ function for hwmon registration,
and drop the remove function entirely.
- if () return; else return; causes static analyzer hiccup.
Please use if () return; return; (no else)
You do that already most of the time but not always.
Thanks,

Though I agree it doesn't really matter, since this code is going to be
removed anyway, so feel free to ignore that one. Just had to make the
point :-)
