-Subject: [PATCH] drm/modes: parse_cmdline: Allow specifying
- stand-alone options
-
-Commit 7b1cce760afe38b40f0989cdf10b2190dccf9815 upstream.
-
-Some options which can be specified on the commandline, such as
-margin_right=..., margin_left=..., etc. are applied not only to the
-specified mode, but to all modes. As such it would be nice if the user
-can simply say e.g.
-video=HDMI-1:margin_right=14,margin_left=24,margin_bottom=36,margin_top=42
-
-This commit refactors drm_mode_parse_command_line_for_connector() to
-add support for this, and as a nice side effect also cleans up the
-function a bit.
