I suppose then what I'll do is request a done callback, and when an LED
update comes in while not done, just save it into a new 'next state
should be' variable, which is compared when done so that at worst I
loose events, but not the final status.

Can I use pmu_request from within the done callback with the same
structure? Probably not a good idea right? I can schedule_work then.
