Merge series "MAINTAINER entries for few ROHM power devices" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:

Add maintainer entries to a few ROHM devices and Linear Ranges

Linear Ranges helpers were refactored out of regulator core to lib so
that other drivers could utilize them too. (I guess power/supply drivers
and possibly clk drivers can benefit from them). As regulators is
currently the main user it makes sense the changes to linear_ranges go
through Mark's tree.

During past two years few ROHM PMIC drivers have been added to
mainstream. They deserve a supporter from ROHM side too :)

Patch 1:
	Maintainer entries for few ROHM IC drivers
Patch 2:
	Maintainer entry for linear ranges helpers
