The practical impact of this patch series on fujitsu-laptop is obviously
very minor assuming the new acpi_video_get_backlight_types() function
functions as advertised.  Accordingly, as maintainer of fujitsu-laptop I
will defer to the opinions of others who maintain the lower level
infrastructure which is more substantially affected by the bulk of the
changes in this series.

I note that Hans has naked the series and I'm happy to go along with that.
