rtc: disable uie before setting time and enable after ...
commit 7e7c005b4b1f1f169bcc4b2c3a40085ecc663df2 upstream.
When setting the time in the future with the uie timer enabled,
rtc_timer_do_work will loop for a while because the expiration of the uie
timer was way before the current RTC time and a new timer will be enqueued
until the current rtc time is reached.
If the uie timer is enabled, disable it before setting the time and enable
it after expiring current timers (which may actually be an alarm).
This is the safest thing to do to ensure the uie timer is still
synchronized with the RTC, especially in the UIE emulation case.
