iwmc3200wifi: Return proper error for iwm_if_alloc
In the case of alloc_netdev_mq failure and kmalloc failure, current implementation returns ERR_PTR(0). As a result, the caller of iwm_if_alloc does not catch the error by IS_ERR macro. Fix it by setting proper error code for ret variable in the failure cases. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
