From: Greg KH <gregkh@linuxfoundation.org>
3.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stanislaw Gruszka <sgruszka@redhat.com>
commit deee0214def5d8a32b8112f11d9c2b1696e9c0cb upstream.
We can not pass NULL libconf->conf->channel to rt61pci_config() as it is dereferenced unconditionally in rt61pci_config_lna_gain() subroutine.
