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