Thanks for the fixes, this looks okay now. However, was there a reason for
not squashing change into your previous patch that introduced the issues
this fixes? That hasn't been applied yet either as far as I'm aware. I'd prefer
we do that and submit a single, good patch if we can.

First patch has already been applied to LF openbmc kernel and being used by many
people so I wanted to keep this clean.
