staging: csr: info leak in unifi_cfg_get_info()
"cfg_ap_config" has a number of fields which are not cleared before we copy them to the user. I've added a memset() at the beginning to set everything to zero. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
