I guess we should warn the driver authors, then; and decide what
driver authors should do.
If I'm video4linux driver for grabbing screen, have been suspended,
and someone asks me to read a frame, should I

b) just block the caller

a) seems ugly to my eyes (userspace should not know about suspend).
