[PATCH 1/2] mfd: Convert WM831x SPI to use dev_pm_ops

From: Mark Brown
Date: Tue Feb 01 2011 - 06:46:22 EST


There is a move to deprecate bus-specific PM operations and move to
using dev_pm_ops instead in order to reduce the amount of boilerplate
code in buses and facilitiate updates to the PM core. Do this move for
the WM831x SPI driver.
