Subject: [PATCH v2 17/29] ACPI: video: Add Apple GMUX brightness control detection
Date: Tue, 12 Jul 2022 21:38:58 +0200 [thread overview]
Message-ID: <20220712193910.439171-18-hdegoede@redhat.com> (raw)
In-Reply-To: <20220712193910.439171-1-hdegoede@redhat.com>
On Apple laptops with an Apple GMUX using this for brightness control,
should take precedence of any other brightness control methods.
Add apple-gmux detection to acpi_video_get_backlight_type() using
the already existing apple_gmux_present() helper function.
This will allow removig the (ab)use of:
acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);
Inside the apple-gmux driver.
