[GIT PULL] Immutable backlight-detect-refactor branch between acpi, drm-* and pdx86

[Hans de Goede]

Hi All,

Now that all patches have been reviewed/acked here is an immutable backlight-detect-refactor
branch with 6.0-rc1 + the v5 patch-set, for merging into the relevant (acpi, drm-* and pdx86)
subsystems.

Please pull this branch into the relevant subsystems.

I will merge this into the review-hans branch of the pdx86 git tree today and
from there it will move to for-next once the builders have successfully build-tested
the merge.

Regards,

Hans
