Once a driver has been matched and probe() returns with -EPROBE_DEFER the
device is added to a deferred list and will be retried later.
At this point __device_attach_driver() should stop trying other drivers as
we have "matched" this driver and already scheduled another probe to
happen later.
Return the -EPROBE_DEFER from really_probe() instead of squashing it to
zero. This is similar to the code at the top of the function which
directly returns -EPROBE_DEFER.
It is not really a bug as, AFAIK, we don't actually have cases where
multiple drivers can bind.
