Subject: mfd: Refactor db8500-prcmu request_clock() function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e62ccf3a7a21d62d92520f47ba5bd7e2112d8c1b;p=mv-sheeva.git

mfd: Refactor db8500-prcmu request_clock() function

This refactors the mfd/dbx500-prcmu drivers to use a switch()
statement rather than nested if/else-construction.
