[ibm-acpi-devel] [PATCH v5 5/6] platform: x86: dell-laptop: Set keyboard backlight led device default trigger

[Hans de G. <hde...@re...>]

Set kbd_led.default_trigger to "kbd-backlight", this will allow user
space to be notified of brightness changes through
ledtrig_kbd_backlight().

Note this also sets the LED_TRIGGER_READ_ONLY flag since the brightness
is hardwired to be controlled by the kbd-backlight hotkey.
