Subject: [media] staging/as102: convert set_fontend to use DVBv5 parameters
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dfc6438410ebe2b9858aaf41376f35a0a68eeb4b;p=linux-beck.git

[media] staging/as102: 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.
