[PATCH] Fix RTC_AIE with CONFIG_HPET_EMULATE_RTC

From: Bernhard Walle
Date: Thu Dec 20 2007 - 09:49:30 EST


In the current code, RTC_AIE doesn't work if the RTC relies on
CONFIG_HPET_EMULATE_RTC because the code sets the RTC_AIE flag
in hpet_set_rtc_irq_bit(). The interrupt handles does accidentally
check for RTC_PIE and not RTC_AIE when comparing the time
which was set in hpet_set_alarm_time().

This patch is against 2.6.24-rc5-mm1.
