From: Daniel Vetter Date: Wed, 8 Aug 2012 21:35:37 +0000 (+0200) Subject: drm/i915: DE_PCU_EVENT irq is ilk-only X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=73edd18f610b6dd900cc3a180919dc643fff8513;p=deliverable%2Flinux.git drm/i915: DE_PCU_EVENT irq is ilk-only Like all the other drps/ips stuff. Hence add the corresponding check, give the function a preciser prefix and move the single reg clearing into the rps handling function, too.
