drivers/media/usb/dvb-usb/dvb-usb-dvb.c: In function ‘dvb_usb_adapter_frontend_init’:
drivers/media/usb/dvb-usb/dvb-usb-dvb.c:323: warning: ‘ret’ is used uninitialized in this function
If num_frontends is zero, dvb_usb_adapter_frontend_init() will return an
uninitialized value. Initialize ret to -ENODEV to fix this.

Can num_frontends ever be zero?
