[linux-dvb] [PATCH] fix NULL pointer dereference in NOVA T USB2 Remote Control

This patch fixes the NULL pointer exception while using the Remote
Control for a NOVA T USB2.

Basically this line was missing (for the properties of the device
"dvb_usb_device_properties")

       .size_of_priv     = sizeof(struct dibusb_state),

I'm not sure the fix is 100% correct since the same line is present
for the properties of the adapter (dvb_usb_device_adapter_properties),
both at around line 154 of
/linux/drivers/media/dvb/dvb-usb/nova-t-usb2.c.

The question is: the "struct dibusb_state" should be allocated for

1) the device
2) the adapter
3) both

?

Should the patch remove the allocation of "priv" for the adapter?

Any suggestions?

Thanks
