From fa4b2a171d42ffc512b3a86922ad68e1355eb17a Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 5 Jan 2012 08:07:32 -0200 Subject: [PATCH] [media] drxk: create only one frontend for both DVB-C and DVB-T Instead of creating two DVB frontend entries for the same device, create just one entry, and fill the delivery_system according with the supported standards.
