HID: asus: only support backlight when it's not driven by WMI
The Asus GL502VSK has the same 0B05:1837 keyboard as we've seen in
several Republic of Gamers laptops.
However, in this model, the keybard backlight control exposed by hid-asus
has no effect on the keyboard backlight. Instead, the keyboard
backlight is correctly driven by asus-wmi.
With two keyboard backlight devices available (and only the acer-wmi
one working), GNOME is picking the wrong one to drive in the UI.
Avoid this problem by not creating the backlight interface when we
detect a WMI-driven keyboard backlight.
We have also tested Asus GL702VMK which does have the hid-asus
backlight present, and it still works fine with this patch (WMI method
call returns UNSUPPORTED_METHOD).
A direct "depends on ASUS_WMI" is intentionally avoided so that HID_ASUS
users who have ASUS_WMI=n will not quietly lose their HID_ASUS driver on
a kernel upgrade.
