From: Lars-Peter Clausen Date: Mon, 16 Apr 2012 13:16:18 +0000 (+0200) Subject: drm: Fix EDID color format parsing X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ee58808deca66bd0879562abf606e171752e8e15;p=linux-beck.git drm: Fix EDID color format parsing The code should obviously check the EDID feature field for EDID feature flags and not the color_formats field of the drm_display_info struct. Also update the color_formats field with new modes instead of overwriting the current mode.
