The original asus-wmi queues a work which calls the ACPI/WMI methods to
update the keyboard LED brightness. Similar drivers - acer-wmi,
dell-wmi-led just call the ACPI/WMI methods directly without workqueues.
This patch simplifies the keyboard brightness updating process which
calls the kbd_led_update function directly without workqueue in
asus-wmi.
