Re: [PATCH RFC 04/91] [media] af9013: convert set_fontend to use DVBv5 parameters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello
basically I am done all these changes when rewrote whole af9013 driver. Fist PULL request is sent one month ago and I resend it last week. Could you apply that first?

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.
