Hi Rafael,
This patch series consists of 2 parts:
1. Fix missing acpi_video# devices on some systems, currently in kernels
>= 6.1.5 and >= 6.2.0 acpi_video# backlight class devices will only
get registered (by default) when a GPU driver asks for this by calling
acpi_video_register_backlight(). This is causing backlight control to
be missing on some systems.
Patches 1-4 fix this and ideally these should be send to Linus for
an upcoming 6.3-rc# release.
2. Now that the dust has settled a bit on the backlight refactor we can
do some further cleanups. This is done in patches 5 + 6. Note that
patch 5 depends on patch 2.
Regards,
Hans
