ath9k: remove a bogus WARN_ON
On embedded hardware it's normal to not have a PCI device for the PCI bridge that the wifi card is attached to. pdev->bus->self will be NULL in that case. In that case, simply return without emitting an useless kernel stack trace. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
