Hi all,

Any other comments/reviews on this patch set? It's marked as Changes Requested
in Patchwork, but I don't think I saw any discussions that ended up with any
changes being asked for?

Perhaps it was done in anticipation to follow up to Radhey's or
Andrew's question but seems like you answered those. Or maybe because
of the missing CC on of hancock@sedsystems.ca on patch 5?
Not sure.

Could you fold some of the explanations into commit messages, add
Andrew's Acks and post a v3? 

We could probably apply as is but since it was marked as Changes
Requested I can't be sure someone hasn't stopped reviewing in
anticipation of v3.

Thanks!

That's actually my old email address (before the renaming from SED Systems to
Calian AT). I think get_maintainer.pl picks that up as I had some past commits
to the driver with that email.
