qlcnic: fix unchecked return value Function pci_find_ext_capability() may return 0, which is an invalid address. In function qlcnic_sriov_virtid_fn(), its return value is used without validation. This may result in invalid memory access bugs. This patch fixes the bug. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: David S. Miller <davem@davemloft.net>
