Hello Henrik Rydberg,
This is a semi-automatic email about new static checker warnings.
The patch 4fa3a5837b84: "HID: hid-multitouch: Switch to device
groups" from May 1, 2012, leads to the following Smatch complaint:
drivers/hid/hid-multitouch.c:735 mt_probe()
error: we previously assumed 'id' could be null (see line 694)
drivers/hid/hid-multitouch.c
693
694 if (id) {
^^^^
Old check.
695 for (i = 0; mt_classes[i].name ; i++) {
696 if (id->driver_data == mt_classes[i].name) {
697 mtclass = &(mt_classes[i]);
698 break;
699 }
700 }
701 }
702
[snip]
733 mt_post_parse(td);
734
735 if (id->vendor == HID_ANY_ID && id->product == HID_ANY_ID)
^^^^^^^^^^
New dereference removed a check.
736 mt_post_parse_default_settings(td);
737
regards,
dan carpenter
