From d3c76025a7de614fade5ffcaa8c1d88d8d64213e Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 18 Nov 2019 16:51:27 +0100 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,...
