Subject: drivers/rtc/rtc-isl1208.c: call rtc_update_irq() from the alarm irq
handler
From: Jan Luebbe <j...@pengutronix.de>
commit 72fca4a4b32dc778b5b885c3498700e42b610d49 upstream.
Previously the alarm event was not propagated into the RTC subsystem.
By adding a call to rtc_update_irq, this fixes a timeout problem with
the hwclock utility.
