Subject[ 003/149] USB: option: make interface blacklist work again
3.2-stable review patch.  If anyone has any objections, please let me know.


From: Bjørn Mork <>

commit 963940cf472d76eca2d36296e461202cc6997352 upstream.

commit 0d905fd "USB: option: convert Huawei K3765, K4505, K4605
reservered interface to blacklist" accidentally ANDed two
blacklist tests by leaving out a return. This was not noticed
because the two consecutive bracketless if statements made it
syntactically correct.
