From: Imre Deak Date: Wed, 5 Nov 2014 18:48:48 +0000 (+0200) Subject: drm/i915: move rps irq enable/disable to i915_irq.c X-Git-Tag: firefly_0821_release~176^2~2672^2~14^2~107 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b900b949674464d6ede123fb352d3a63690e31ab;p=firefly-linux-kernel-4.4.55.git drm/i915: move rps irq enable/disable to i915_irq.c The logical place for these functions is in i915_irq.c next to the rest of PM interrupt handling functions. No functional change.
