Subject[PATCH 04/21] regulator: da9055: Pass descriptor instead of GPIO number
Date
When setting up a fixed regulator on the DA9055, pass a descriptor
instead of a global GPIO number. This facility is not used in the
kernel so we can easily just say that this should be a descriptor
if/when put to use.

Lee: would be nice if you could ACK this smallish patch
to the MFD header.
