Subject: rt61pci: fix NULL pointer dereference in config_lna_gain
From: Stanislaw Gruszka <[email protected]>
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.
