The commit log text sounds like a harmless optimisation, but the error
message here either means you're fixing a compile failure, or (and?) the
patch was sent out before the commit log was finalized.

Looking at it this is the error message that triggers if you compile
this driver with OF unset. I'd like to have that mentioned, then the
patch looks fine. Ditto for the 2nd patch in this series.

Best regards
Uwe
