[Impact]
[Fix]
[Test]
[Where problems could occur] |
[Impact]
There are acpi_video* sysfs backlight interface in the system which are not working.
For Dell AIO platforms, we use dell_uart_backlight to control the display brightness.
The old way to fix this is to unregister acpi backlight interfaces in the backlight driver, but it may lead to some issues and the unregister function has been removed since v6.1-rc1
77ab9d4d44cd ("ACPI: video: Remove acpi_video_set_dmi_backlight_type()")
[Fix]
The new way to do this is to collect all the quirk and auto detection method in video_detect.c
I added an audo detection for the Dell AIO platoform to the driver which should do the same thing as the old way.
[Test]
Verified on the Dell AIO platform and confirmed there is only on dell_uart_backlight in the sysfs, and no acpi_video* interface.
[Where problems could occur]
There should be no regression potential, it uses different way to do the same thing, should be pretty safe. |
