Hello Ram Amrani,
This is a semi-automatic email about new static checker warnings.
The patch abd49676c707: "qed: Add RoCE ll2 & GSI support" from Oct 1,
2016, leads to the following Smatch complaint:
drivers/net/ethernet/qlogic/qed/qed_roce.c:2853 qed_roce_ll2_tx()
warn: variable dereferenced before check 'cdev' (see line 2846)
drivers/net/ethernet/qlogic/qed/qed_roce.c
2845 {
2846 struct qed_hwfn *hwfn = QED_LEADING_HWFN(cdev);
^^^^
2847 struct qed_roce_ll2_info *roce_ll2 = hwfn->ll2;
^^^^^^^^^
2848 enum qed_ll2_roce_flavor_type qed_roce_flavor;
2849 u8 flags = 0;
2850 int rc;
2851 int i;
2852
2853 if (!cdev || !pkt || !params) {
^^^^
This one also.
2854 DP_ERR(cdev,
2855 "roce ll2 tx: failed tx because one of the following is NULL - drv=%p, pkt=%p, params=%p\n",
regards,
dan carpenter
