Subject: [media] tda10023: convert set_fontend to use DVBv5 parameters
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=787d92e176943913d7583f0f04e6d89a0014c5b4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[media] tda10023: 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.
