Subject: arm: nomadik: Use local irq state
X-Git-Tag: v3.0~1116^2~95
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d1118f68b66ef6e0f36c9887c504462f2ec02d0d;p=platform%2Fkernel%2Flinux-amlogic.git

arm: nomadik: Use local irq state

Store the enabled mask in the local state, so there is no need to
fiddle in the irq descriptor.
