I'd expect you can drop these log messages, if there's stuff like this
missing we should add it to regmap.  At the minute the regmap logging is
via trace points rather than debug logs as you can leave them enabled
all the time.

Might also be worth moving some of the sysfs stuff to live with the
relevant drivers.
