Realtek RTL8188ETV 2.4 GHz WiFi modules (detected as RTL8188EU by the
RTL8XXXXU driver) are found soldered into some embedded devices, such as
the Fernsehfee 3.0 set-top box.

They require a 3.3V power supply.

checkpatch.pl flags the "usbbda" prefix as undocumented because it isn't
in vendor-prefixes.yaml. It is, however, an established pattern:

$ git grep -E 'usb[0-9a-f]{1,4},[0-9a-f]{1,4}' | wc -l
213


V2:
- Refer to RTL8188ETV in the title and description
