Subject: [media] or51132: convert set_fontend to use DVBv5 parameters
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8f7cc28464bc07dbf055b062ef1dec2cda07032;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[media] or51132: 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.
