That would simplify this patch.

Change cb710-mmc platform driver to register pm ops using dev_pm_ops instead of legacy pm_ops. The existing legacy suspend/resume routines are identical and simply clear IRQ mask in the device in case it got undefined during sleep state. Changed code to collapse suspend and resume into one .pm interface for suspend and resume which gets installed for suspend, freeze, poweroff, thaw, restore, and resume states.
