From: Daniel Vetter Date: Mon, 21 Oct 2013 16:04:36 +0000 (+0200) Subject: drm/i915: refactor ilk display interrupt handling X-Git-Tag: v3.13-rc1~69^2~3^2~20 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=40da17c29be95acf5543c97c8bc2fbb5991c3e39;p=platform%2Fkernel%2Flinux-stable.git drm/i915: refactor ilk display interrupt handling - Use a for_each_loop and add the corresponding #defines. - Drop the _ILK postfix on the existing DE_PIPE_VBLANK macro for consistency with everything else. - Also use macros (and add the missing one for plane flips) for the ivb display interrupt handler.
