Subject: rtc-cmos: fix suspend/resume
From: Paul Fox <[email protected]>
rtc-cmos was setting suspend/resume hooks at the device_driver level.
However, the platform bus code (drivers/base/platform.c) only looks for
resume hooks at the dev_pm_ops level, or within the platform_driver.
Switch rtc_cmos to use dev_pm_ops so that suspend/resume code is executed
again.
