From: Imre Deak Date: Wed, 5 Nov 2014 18:48:37 +0000 (+0200) Subject: drm/i915: unify gen6/gen8 rps irq handler X-Git-Tag: firefly_0821_release~176^2~2672^2~14^2~109 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c9a9a2688256b32af05e4f8c792b243419e41311;p=firefly-linux-kernel-4.4.55.git drm/i915: unify gen6/gen8 rps irq handler After the previous patch the GEN8 RPS handler became very similar to the GEN6 version, so unify the two functions. No functional change.
