drm/modes: parse_cmdline: Add freestanding argument to drm_mode_parse_cmdline_options() (99e2716e) · Commits · 戴 / test

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,... Acked-by:
