Rafael J. Wysocki 421091ae0e rtc: cmos: Disable ACPI RTC event on removal 
[ Upstream commit 83ebb7b303 ]

Make cmos_do_remove() drop the ACPI RTC fixed event handler so as to
prevent it from operating on stale data in case the event triggers
after driver removal.

Fixes: 311ee9c151 ("rtc: cmos: allow using ACPI for RTC alarm instead of HPET")
