Subject: [media] mt312: convert set_fontend to use DVBv5 parameters
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=827b5f3e30296f5ddeedc0c0359b1db77fd499a6;p=~shefty%2Frdma-dev.git

[media] mt312: convert set_fontend to use DVBv5 parameters

Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.

Also, fill the supported delivery systems at dvb_frontend_ops
struct.
