Thanks for moving this one earlier in the series. Looks like
you're missing Samuel as the MFD maintainer from your cc.
You should resend again with Samuel Ortiz <sameo@linux.intel.com>
added.

Maybe check the patches in this series with scripts/get_maintainer.pl
to see who all should be cc:ed?

Regards,

Tony
