drivers/media/dvb/dvb-usb/dibusb-mb.c: NULL dereference

[Adrian Bunk <bunk@stusta.de>]

The Coverity checker spotted the following "we dereference d->fe only 
when we know it's NULL" bug:

<--  snip  -->

...
static int dibusb_dib3000mb_frontend_attach(struct dvb_usb_device *d)
{
...
        if ((d->fe = dib3000mb_attach(&demod_cfg,&d->i2c_adap,&st->ops)) == NULL) {
                d->fe->ops.tuner_ops.init = dvb_usb_tuner_init_i2c;
                d->fe->ops.tuner_ops.set_params = dvb_usb_tuner_set_params_i2c;
                return -ENODEV;
        }
...

<--  snip  -->

    Gentoo kernels are 42 times more popular than SUSE kernels among
    KLive users  (a service by SUSE contractor Andrea Arcangeli that
    gathers data about kernels from many users worldwide).

       There are three kinds of lies: Lies, Damn Lies, and Statistics.
