[PATCH 0/3] Use acpi_video_unregister_backlight instead of acpi_video_unregister in platfrom backlight drivers

[Hans de Goede]

Hi All,

I'm working on cleaning up the currently somewhat convoluted logic to
select which backlight interfaces to register on x86 systems, see:
http://lists.freedesktop.org/archives/dri-devel/2014-December/074687.html

For a rought outline (details will change in the actual patch-set).

These 3 patches are a preparation for that work, as the behavior of the
current code is not always consistent (it changes depending on module
loading order in some cases). These 3 patches remove this inconsistency
which in some cases may result in a behavior change.

This way the cleanup can have a consistent base to build upon, and I can
ensure that the cleanup itself does not cause any functional changes.

I hope to post a v1 of the actual cleanup patch-set in 1-2 weeks.

Regards,

Hans
