From 5a19f312162abd1356cdcda608f2b13502a383cc Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Wed, 2 Aug 2006 08:44:31 -0300 Subject: [PATCH] V4L/DVB (4465): Attach the dib3000mc correctly Flynn Marquardt found out that there is problem with the new dib3000mc-driver when using with the real dib3000mc. It resulted in a segfault. Fixed two things: use the correct I2C address and do not attach a tuner, when the demod was previously failing.
