I'm getting this:

rusb2/pvrusb2: struct usb_device_id is 20 bytes.  The last of 3 is:
0x03 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 
FATAL: drivers/media/video/pvrusb2/pvrusb2: struct usb_device_id is not terminated with a NULL entry!

("rusb2/pvrusb2" ??)

but:

struct usb_device_id pvr2_device_table[] = {
	[PVR2_HDW_TYPE_29XXX] = { USB_DEVICE(0x2040, 0x2900) },
	[PVR2_HDW_TYPE_24XXX] = { USB_DEVICE(0x2040, 0x2400) },
	{ USB_DEVICE(0, 0) },
};
	
looks OK?

Using plain old "{ }" shut the warning up.
