Subject: [media] sp887x: convert set_fontend to use DVBv5 parameters
X-Git-Tag: v3.3-rc1~48^2~269
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5ebffc39929d553f26599976b7393e425a07bd36;p=karo-tx-linux.git

[media] sp887x: 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.
