Return the class of the device NAME for an event generated on FRAME.
NAME is a string that can be the value of last-event-device, or
nil.

But it's not clear what the meaning of nil should be. Perhaps Po Lu

(And if nil really is a meaningful value for NAME, and not just a
documentation error, then perhaps that argument should be optional?)
