| |
backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h.
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.
