[PATCH 01/05 v2] gpio: rcar: Use lazy disable

From: Magnus Damm
Date: Tue Nov 19 2013 - 19:22:33 EST


From: Magnus Damm <damm@xxxxxxxxxxxxx>

Set the ->irq_enable() and ->irq_disable() methods to NULL
to enable lazy disable of interrupts. This by itself provides
some level of optimization, but is mainly enabled as ground
work for future Suspend-to-RAM wake up support.
