[PATCH] Fix manual binding infinite loop

[Greg KH]

Fix for manual binding of drivers to devices.  Problem is if you pass in
a valid device id, but the driver refuses to bind.  Infinite loop as
write() tries to resubmit the data it just sent.

Thanks to Michal Ostrowski <mostrows@xxxxxxxxxxxxxx> for pointing the
problem out.
