Tue, 07 Mar 2023 13:05:40 +0100

backlight: apple_bl: Use acpi_video_get_backlight_type()On some MacBooks both the apple_bl and the apple-gmux backlight driversmay be able to export a /sys/class/backlight device.To avoid having 2 backlight devices for one LCD panel until nowthe apple-gmux driver has been calling apple_bl_unregister() to movethe apple_bl backlight device out of the way when it loads.Similar problems exist on other x86 laptops and all backlight driverswhich may be used on x86 laptops have moved to usingacpi_video_get_backlight_type() to determine whether they should loador not.Switch apple_bl to this model too, so that it is consistent with allthe other x86 backlight drivers.Besides code-simplification and consistency this has 2 other benefits:1) It removes a race during boot where userspace will briefly see an apple_bl backlight and then have it disappear again, leading to e.g.: https://bbs.archlinux.org/viewtopic.php?id=2699202) This allows user to switch between the drivers by passing acpi_backlight=apple_gmux or acpi_backlight=vendor on the kernel commandline.Signed-off-by: Hans de Goede Reviewed-by: Daniel Thompson Acked-by: Lee Jones Link: https://lore.kernel.org/r/20230307120540.389920-1-hdegoede@redhat.com List of files: /linux/drivers/video/backlight/Kconfig
