From: Ville Syrjälä Date: Mon, 14 Sep 2015 19:43:45 +0000 (+0300) Subject: drm: Kill pixeldur_ns X-Git-Tag: firefly_0821_release~176^2~721^2~34^2~13 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=20b2020334110f9afb8316ba158b9549f2f07ff9;p=firefly-linux-kernel-4.4.55.git drm: Kill pixeldur_ns pixeldur_ns is now unsued, so kill it from drm_vblank_crtc. framedur_ns is also currently unused but we will have use for it in the near future so leave it be. linedur_ns is still used by nouveau for some internal delays.
