Subject: ACPI: video: Allow selecting NVidia-WMI-EC or Apple GMUX backlight from the cmdline
From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit 420a1116aef0e8e12c305508f45ce73e5ae30a09 upstream.
The patches adding NVidia-WMI-EC and Apple GMUX backlight detection
support to acpi_video_get_backlight_type(), forgot to update
acpi_video_parse_cmdline() to allow manually selecting these from
the commandline.
Add support for these to acpi_video_parse_cmdline().
Fixes: fe7aebb40d42 ("ACPI: video: Add Nvidia WMI EC brightness control detection (v3)")
Fixes: 21245df307cb ("ACPI: video: Add Apple GMUX brightness control detection")
