3.5.7.6 -stable review patch.  If anyone has any objections, please let me know.

------------------

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.
