From fd6072122fac77b8a5ff5891ee89a208aaab8f25 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 22 Dec 2011 10:14:08 -0300 Subject: [PATCH] [media] cx22700: 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.
