[RFC PATCH 0/2] rtc: fix race condition between uie enable and rtc set time

From: Yu Liao
Date: Tue Oct 25 2022 - 23:35:03 EST


The patch series fixes two issues in rtc_set_time caused by race
conditions:
- rtc_timer_do_work will loop for a while when setting rtc time in the
future with uie enabled.
- RTC_UIE_OFF does not work when RTC_UIE_OFF and RTC_SET_TIME are
running in parallel.

Patch #1 extracts lockless version from rtc_update_irq_enable, and
patch #2 addresses the race condition issue.

Yu Liao (2):
rtc: add lockless rtc_update_irq_enable
rtc: fix race condition in rtc_set_time()
