Michał Kępień 5959ddd02b platform/x86: fujitsu-laptop: account for backlight power when determining brightness
The comment for the get_brightness backlight device callback in
include/linux/backlight.h states that it should "return the current
backlight brightness (accounting for power, fb_blank etc.)".
fujitsu-laptop violates that premise by simply returning the value to
which ACPI function GBLL evaluates to.  Make sure 0 is returned when
backlight power is turned off.
