Hello Atul Deshmukh,
This is a semi-automatic email about new static checker warnings.
The patch ef4647420025: "[SCSI] qla2xxx: Add support for ISP8044."
from Aug 27, 2013, leads to the following Smatch complaint:
drivers/scsi/qla2xxx/qla_os.c:2962 qla2x00_probe_one()
error: we previously assumed 'base_vha' could be null (see line 2632)
drivers/scsi/qla2xxx/qla_os.c
2631 base_vha = qla2x00_create_host(sht, ha);
2632 if (!base_vha) {
^^^^^^^^
Existing check.
2633 ret = -ENOMEM;
2634 qla2x00_mem_free(ha);
2635 qla2x00_free_req_que(ha, req);
2636 qla2x00_free_rsp_que(ha, rsp);
2637 goto probe_hw_failed;
2638 }
[ snip ]
2954 probe_hw_failed:
2955 if (IS_QLA82XX(ha)) {
2956 qla82xx_idc_lock(ha);
2957 qla82xx_clear_drv_active(ha);
2958 qla82xx_idc_unlock(ha);
2959 }
2960 if (IS_QLA8044(ha)) {
2961 qla8044_idc_lock(ha);
2962 qla8044_clear_drv_active(base_vha);
^^^^^^^^
Patch adds dereference.
2963 qla8044_idc_unlock(ha);
2964 }
regards,
dan carpenter
