[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. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
