4 Subject: [PATCH] drm/modes: parse_cmdline: Add freestanding argument
5 to drm_mode_parse_cmdline_options()
6
7 Commit 99e2716e053734b70434502867be24d20a3e2d84 upstream.
8
9 Add a freestanding function argument to drm_mode_parse_cmdline_options()
10 similar to how drm_mode_parse_cmdline_extra() already has this.
11
12 This is a preparation patch for allowing parsing of stand-alone options
13 without a mode before them, e.g.: video=HDMI-1:margin_right=14,...
