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 <sa...@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
