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,...
