[Bug 1034562] [NEW] atkbd serio0: Unknown key pressed: code 0xc4

[Aapo Rantalainen]

Public bug reported:

Laptop has button (+led) for enabling built-in 3G-modem. Pressing it will enable modem (and switch on the led), but it also gives error: 
[  199.099227] atkbd serio0: Unknown key pressed (translated set 2, code 0xc4 on isa0060/serio0).
[  199.099235] atkbd serio0: Use 'setkeycodes e044 <keycode>' to make it known.

Pressing again will disable the modem (and switch off the led), and also gives error:
[  270.891553] atkbd serio0: Unknown key released (translated set 2, code 0xba on isa0060/serio0).
[  270.891560] atkbd serio0: Use 'setkeycodes e03a <keycode>' to make it known.
