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
