Hello Cai Huoqing,
This is a semi-automatic email about new static checker warnings.
The patch 2acf960e3be6: "net: hinic: Add support for configuration of
rx-vlan-filter by ethtool" from Nov 3, 2022, leads to the following
Smatch complaint:
drivers/net/ethernet/huawei/hinic/hinic_port.c:459 hinic_set_vlan_fliter()
^^^^
This should be "filter" instead of "fliter" (swap the li).
warn: variable dereferenced before check 'hwdev' (see line 453)
drivers/net/ethernet/huawei/hinic/hinic_port.c
452 struct hinic_hwdev *hwdev = nic_dev->hwdev;
453 struct hinic_hwif *hwif = hwdev->hwif;
^^^^^^^^^^^
Dereference.
454 struct pci_dev *pdev = hwif->pdev;
455 struct hinic_vlan_filter vlan_filter;
456 u16 out_size = sizeof(vlan_filter);
457 int err;
458
459 if (!hwdev)
^^^^^^
Checked too late.
460 return -EINVAL;
461
regards,
dan carpenter
