I do not think we should be adding this as is as it seems to be very
wacom-specific. I'd rather call it something else, like SW_MUTE_DEVICE
or similar.

I also wonder if this should really be a switch: can you query it's
state? What happen if user plugs in the device, engages the switch and
then [re]loads the driver? Will the state be still signalled properly?
What about suspend/resume or hibernation?

Thanks.
