Subject: gpio: rcar: Use lazy disable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fba968a1e6b84be01e548f4b28b78e0542f3adaa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

gpio: rcar: Use lazy disable

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.
