Hello Dmitry Torokhov,

This is a semi-automatic email about new static checker warnings.

The patch b5d21704361e: "Input: psmouse - switch to using dev_*() for
messages" from Oct 10, 2011, leads to the following Smatch complaint:

drivers/input/mouse/psmouse-base.c:1512 psmouse_reconnect()
	 error: we previously assumed 'psmouse' could be null (see line 1511)

drivers/input/mouse/psmouse-base.c
  1510	
  1511		if (!drv || !psmouse) {
                             ^^^^^^^
Old check.

  1512			psmouse_dbg(psmouse,
                                    ^^^^^^^
New dereference.

  1513				    "reconnect request, but serio is disconnected, ignoring...\n");
  1514			return -1;

regards,
dan carpenter
