All x86/ACPI kms drivers which register native/BACKLIGHT_RAW type backlight devices call acpi_video_backlight_use_native() now. This sets __acpi_video_get_backlight_type()'s internal static native_available flag. This makes the backlight_device_get_by_type(BACKLIGHT_RAW) check unnecessary. Relying on the cached native_available value not only is simpler, it will also work correctly in cases where then native backlight registration was skipped because of acpi_video_backlight_use_native() returning false.
