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:2812 qed_roce_ll2_stop()
warn: variable dereferenced before check 'cdev' (see line 2808)
drivers/net/ethernet/qlogic/qed/qed_roce.c
2807 {
2808 struct qed_hwfn *hwfn = QED_LEADING_HWFN(cdev);
2809 struct qed_roce_ll2_info *roce_ll2 = hwfn->ll2;
^^^^^^^^^
Deref.
2810 int rc;
2811
2812 if (!cdev) {
^^^^^
Checked too late.
2813 DP_ERR(cdev, "qed roce ll2 stop: invalid cdev\n");
2814 return -EINVAL;
regards,
dan carpenter
