The patch titled rtc-cmos: fix suspend/resume has been removed from the -mm tree. Its filename was rtc-cmos-fix-suspend-resume.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: rtc-cmos: fix suspend/resume From: Paul Fox <pgf@xxxxxxxxxx> 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. Paul said: : The user visible symptom in our (XO laptop) case was that rtcwake would : fail to wake the laptop. The RTC alarm would expire, but the wakeup : wasn't unmasked. : : As for severity, the impact may have been reduced because if I recall : correctly, the bug only affected platforms with CONFIG_PNP disabled.
