rtc: xgene: fix possible race condition

2019-05-31T13:43:40Z

[ Upstream commit a652e00ee1233e251a337c28e18a1da59224e5ce ] The IRQ is requested before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc struct before requesting the IRQ.

rtc: stop validating rtc_time after rtc_time_to_tm

2018-03-01T09:49:41Z

rtc_time_to_tm never generates an invalid tm. It is not necessary to validate it. Signed-off-by: Alexandre Belloni

rtc: xgene: mark PM functions as __maybe_unused

2017-11-09T00:25:47Z

The new xgene_rtc_alarm_irq_enabled() function is only accessed from PM code, which is inside of an #ifdef; this causes a harmless build warning when CONFIG_PM is disabled: drivers/rtc/rtc-xgene.c:108:12: error: 'xgene_rtc_alarm_irq_enabled' defined but not used [-Werror=unused-function] Just remove the #ifdef and use __maybe_unused annotations instead, to make the code more robust here.
