Subject: [PATCH] drm/modes: parse_cmdline: Stop parsing extras after
|
|
bpp / refresh at ', '
|
|
|
|
Commit c2ed3e941901810ad3d55ce1935fa22c5007fee4 upstream.
|
|
|
|
Before this commit it was impossible to add an extra mode argument after
|
|
a bpp or refresh specifier, combined with an option, e.g.
|
|
video=HDMI-1:720x480-24e,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 fixing the length calculation if extras_ptr
|
|
is set to stop the extra parsing at the start of the options (stop at the
|
|
',' options_ptr points to).
