[PATCH v2 03/11] ARM: S3C24XX: cleanup irq-pm integration
Heiko Stübner

Tue Jan 1 16:54:48 EST 2013
This patch integrates the irq-pm functions we moved in the previous patch.
This includes some static attributes and the removal of the irq suspend
and resume declaratons from the plat-samsung/pm.h header.
