But does the actual error already get logged somewhere?
(I don't see where.)
Some _do_event() failures are reported, others aren't.  I don't see
why there's a distinction.

A DM_EVENT_CMD_REGISTER_FOR_EVENT failure is logged.
A DM_EVENT_CMD_GET_TIMEOUT failure is not.

Surely these failures should never occur on a properly-running system, so why
not log them all in a similar way?
