Hello Jason Gerecke,
This is a semi-automatic email about new static checker warnings.
The patch 2a6cdbdd4cc0: "HID: wacom: Introduce new 'touch_input'
device" from Jun 15, 2015, leads to the following Smatch complaint:
drivers/hid/wacom_wac.c:1586 wacom_tpc_irq()
error: we previously assumed 'wacom->touch_input' could be null (see line 1577)
drivers/hid/wacom_wac.c
1576 "%s: received report #%d\n", __func__, data[0]);
1577 else if (wacom->touch_input)
^^^^^^^^^^^^^^^^^^
Patch adds new check for NULL.
1578 dev_dbg(wacom->touch_input->dev.parent,
1579 "%s: received report #%d\n", __func__, data[0]);
1580
1581 switch (len) {
1582 case WACOM_PKGLEN_TPC1FG:
1583 return wacom_tpc_single_touch(wacom, len);
1584
1585 case WACOM_PKGLEN_TPC2FG:
1586 return wacom_tpc_mt_touch(wacom);
^^^^^
Not checked inside this function call.
1587
1588 case WACOM_PKGLEN_PENABLED:
regards,
dan carpenter
