drivers/rtc/rtc-mrst: fix suspend/resume
The Moorestown RTC driver implements suspend and resume callbacks and assigns them to the suspend and resume fields of the device_driver struct. These callbacks are never actually called by anything though. Modify the driver to properly use dev_pm_ops so that the suspend and resume functions are actually executed upon suspend/resume. [akpm@linux-foundation.org: device_driver.name is const char *] Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Feng Tang <feng.tang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
