Hi!
The attached adds support for using multiproto drivers with the old api.

From: Anssi Hannula <anssi.hannula@xxxxxxxxx>
multiproto: add support for using multiproto drivers with old api
Allow using multiproto drivers with the old API. Multiproto drivers
will provide one frontend type over the old API. For STB0899 this is
FE_QPSK. olddrv_to_newapi() and newapi_to_olddrv() are renamed to
oldapi_to_newapi() and newapi_to_oldapi(), respectively.
