Now that all kms drivers which register native/BACKLIGHT_RAW type backlight devices on x86/ACPI boards call acpi_video_get_backlight_type(true), with the native=true value getting cached, there no longer is a need to call backlight_device_get_by_type(BACKLIGHT_RAW) to see if a native backlight device is available. 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 the acpi_video_get_backlight_type() return value.
