Hello Antti Palosaari,

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

The patch d10d1b9ac97b: "[media] dvb_usb_v2: use dev_* logging
macros" from Jun 26, 2012, leads to the following Smatch complaint:

drivers/media/usb/dvb-usb-v2/dvb_usb_urb.c:31 dvb_usb_v2_generic_io()
         error: we previously assumed 'd' could be null (see line 29)

drivers/media/usb/dvb-usb-v2/dvb_usb_urb.c
    28  
    29          if (!d || !wbuf || !wlen || 
!d->props->generic_bulk_ctrl_endpoint ||
                    ^^
Old check.

    30                          !d->props->generic_bulk_ctrl_endpoint_response) 
{
    31                  dev_dbg(&d->udev->dev, "%s: failed=%d\n", __func__, 
-EINVAL);
                                ^^^^^^^^^^^^^
New dereference.

    32                  return -EINVAL;
    33          }

regards,
dan carpenter
