From 5097f23fd0dd7f3b82f9ebe424274041ad184b2b Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sat, 9 Feb 2008 10:29:52 -0600 Subject: pvrusb2-dvb: Don't initialize if device lacks a digital side From: Mike Isely In the end we'd like the dvb interface to always be present - even for analog devices (via the mpeg encoder). However right now pvrusb2-dvb won't operate correctly if the hardware doesn't have a digital tuner, so don't initialize the DVB interface unless we know we have a digital tuner.
