Subject: [PATCH] drm/modes: parse_cmdline: Accept extras directly
|
|
after mode combined with options
|
|
|
|
Commit cfb0881b8f621b656a9e23b31944a5db94cf5842 upstream.
|
|
|
|
Before this commit it was impossible to combine an extra mode argument
|
|
specified directly after the resolution with an option, e.g.
|
|
video=HDMI-1:720x480e,rotate=180 would not work, either the "e" to force
|
|
enable would need to be dropped or the ",rotate=180", otherwise the
|
|
mode_option would not be accepted.
|
|
|
|
This commit fixes this by setting parse_extras to true in this case, so
|
|
that drm_mode_parse_cmdline_res_mode() parses the extra arguments directly
|
|
after the resolution.
