Subject: regulator: mp5416: use OF match data
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=df43c245dd0535f6e2256e0261d43a4dd72b8b28;p=linux.git

regulator: mp5416: use OF match data

In preparation for adding support for MP5496 which slightly differs from
MP5416 convert the driver to use OF match data instead of always using the
MP5416 regulator_desc for regulator registration.
