[PATCH 2/2] arm: exynos: Clear ENABLE_WAKEUP_SW bit when entering suspend

From: Doug Anderson
Date: Tue Mar 19 2013 - 12:52:26 EST


From: Jonathan Kliegman <kliegs@xxxxxxxxxxxx>

Setting this bit to 0 causes the system to wait until suspended
to use the wakeup masks. With it being set high previously,
masked interrupts were being received and processed before the
EINT_WAKEUP_MASK was configured.
