[PATCH 7/7] Update the AV7110 DVB driver

From: LinuxTV.org CVS maintainer
Date: Thu Oct 09 2003 - 06:05:04 EST


- [DVB] add vbi device handling for dvb-c cards with analog module
- [DVB] fix error handling upon device initialization
- [DVB] fix DD1_INIT handling of DVB-C w/ analog module installed. (Jon Burgess)
