From: Daniel Vetter Date: Wed, 16 Oct 2013 20:55:46 +0000 (+0200) Subject: drm/i915: extract display_pipe_crc_update X-Git-Tag: v3.13-rc1~69^2~3^2~60 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eba94eb90138caf0b22797dc5fd802e28d253dcf;p=platform%2Fkernel%2Flinux-stable.git drm/i915: extract display_pipe_crc_update The ringbuffer update logic should always be the same, but different platforms have different amounts of CRC registers. Hence extract it.
