I would rather use different name as kbd_phantom_backlight. E.g.
lbd_broken_backlight or something which indicates non-working / disabled
support.

Also in commit message is written that problem is with KBD_LED_OFF_TOKEN
and KBD_LED_ON_TOKEN tokens, but proposed patch does not blacklist these
tokens, but rather turn off whole kbd functionality. So proposed patch
does not patch commit message, nor explain it.
