From ed5452a2ab90e4936572807debada676e36e2efe Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 26 Dec 2011 09:57:11 -0300 Subject: [PATCH] [media] drxk: 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.
