From: Cornelia Huck <[EMAIL PROTECTED]>
Don't stop on the first ->probe error that is not -ENODEV/-ENXIO.
There might be a driver registered returning an unresonable return code, and
this stops probing completely even though it may make sense to try the next
possible driver. At worst, we may end up with an unbound device.
