4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <dan.carpen...@oracle.com> commit ac0e89bb4744d3882ccd275f2416d9ce22f4e1e7 upstream. We use logical negate where bitwise negate was intended. It means that we never return -EINVAL here.
