Subject[PATCH 3/4] backlight: ipaq_micro: Use backlight helper
Date
Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.
