Hello Alexandre Bounine,
This is a semi-automatic email about new static checker warnings.
The patch b6e8d4aa1110: "rapidio: add RapidIO channelized messaging
driver" from Aug 2, 2016, leads to the following Smatch complaint:
drivers/rapidio/rio_cm.c:1220 riocm_ch_listen()
error: we previously assumed 'ch' could be null (see line 1218)
drivers/rapidio/rio_cm.c
1217 ch = riocm_get_channel(ch_id);
1218 if (!ch || !riocm_cmp_exch(ch, RIO_CM_CHAN_BOUND, RIO_CM_LISTEN))
^^^
Check.
1219 ret = -EINVAL;
1220 riocm_put_channel(ch);
^^
Unchecked dereference.
1221 return ret;
1222 }
regards,
dan carpenter
