thank you so much for your answers! I would like to send you
a non-patch of the updated driver shortly if I may; it will
require more testing before submission, but having your blessing
first should make things turn around faster.

Depens on the kind of suspend - manual suspend will cause open to
fail. Autosuspend (if driver implements it) should resume the device.

I feel a bit reluctant to implement this particular behavior, since it
will leave the device in a bad state; if resume fails and stays suspended,
the device cannot later be opened according to 3). What if a failed
resume leaves the device in state (!opened,!suspended)? It could then
later be reopened.
