Olof, Benson,

Could at least the following patch in this series [1] picked as soon as possible
if it's ok.

9630769 New [01/13] mfd: cros_ec: Add helper for event notifier

This specific patch is blocking this and others like the rtc-cros-ec to land and
the series were send some time ago without received bad feedback.
