Hello Alexander Shishkin,
This is a semi-automatic email about new static checker warnings.
The patch 5f36e231e9db: "usb: chipidea: add support for roles" from
May 11, 2012, leads to the following Smatch complaint:
drivers/usb/chipidea/udc.c:1650 udc_start()
warn: variable dereferenced before check 'udc' (see line 1647)
drivers/usb/chipidea/udc.c
1646 {
1647 struct device *dev = udc->dev;
^^^^^^^^
New dereference.
1648 int retval = 0;
1649
1650 if (!udc)
^^^^
New check.
1651 return -EINVAL;
1652
regards,
dan carpenter
