Hello Matthew R. Ochs,
This is a semi-automatic email about new static checker warnings.
The patch 3065267a80c8: "scsi: cxlflash: Add hardware queues
attribute" from Apr 12, 2017, leads to the following Smatch complaint:
drivers/scsi/cxlflash/main.c:722 term_afu()
warn: variable dereferenced before check 'cfg->afu' (see line 719)
drivers/scsi/cxlflash/main.c
718 */
719 for (k = cfg->afu->num_hwqs - 1; k >= 0; k--)
^^^^^^^^
Patch introduces a new dereference.
720 term_intr(cfg, UNMAP_THREE, k);
721
722 if (cfg->afu)
^^^^^^^^
But the existing code assumed it could be NULL. Presumably it can't?
723 stop_afu(cfg);
724
regards,
dan carpenter
