[PATCH] Fix manual binding infinite loop
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@watson.ibm.com> for pointing the
problem out.
