From: Sascha Hauer Date: Wed, 1 Feb 2012 10:38:23 +0000 (+0100) Subject: drm: add proper return value for drm_mode_crtc_set_gamma_size X-Git-Tag: upstream/snapshot3+hdmi~7918^2~106 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4cae5b84628d5df76247d494e51b89d07e28e6aa;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git drm: add proper return value for drm_mode_crtc_set_gamma_size drm_mode_crtc_set_gamma_size returns boolean true for success and false for failure. This is not very kernel conform, so change it to return 0 for success and a propert error code otherwise. Noone checks the return value, so no users have to be fixed.
