Hello Ram Amrani,
This is a semi-automatic email about new static checker warnings.
The patch 048867793046: "qedr: Add GSI support" from Oct 10, 2016,
leads to the following Smatch complaint:
drivers/infiniband/hw/qedr/qedr_cm.c:284 qedr_gsi_build_header()
warn: variable dereferenced before check 'sgid_attr.ndev' (see line 281)
drivers/infiniband/hw/qedr/qedr_cm.c
280
281 vlan_id = rdma_vlan_dev_vlan_id(sgid_attr.ndev);
^^^^^^^^^^^^^^
Dereference inside function.
282 if (vlan_id < VLAN_CFI_MASK)
283 has_vlan = true;
284 if (sgid_attr.ndev)
^^^^^^^^^^^^^^
Check too late.
285 dev_put(sgid_attr.ndev);
286
regards,
dan carpenter
