Hello Joe Perches,
This is a semi-automatic email about new static checker warnings.
The patch 3567318a63ff: "pktcdvd: add struct pktcdvd_device * to
pkt_dbg" from Aug 1, 2013, leads to the following Smatch complaint:
drivers/block/pktcdvd.c:2844 pkt_remove_dev()
error: we previously assumed 'pd' could be null (see line 2840)
drivers/block/pktcdvd.c
2839 pd = pkt_devs[idx];
2840 if (pd && (pd->pkt_dev == pkt_dev))
^^
Old check.
2841 break;
2842 }
2843 if (idx == MAX_WRITERS) {
2844 pkt_dbg(1, pd, "dev not setup\n");
^^
New dereference.
2845 ret = -ENXIO;
2846 goto out;
regards,
dan carpenter
