From 304dfa39df9db3695e21bd87ac2c84819c889359 Mon Sep 17 00:00:00 2001 From: Andrew de Quincey Date: Thu, 4 May 2006 16:39:44 +0100 Subject: Fix CI interface on KNC1 DVBT and DVBC cards From: Andrew de Quincey These cards need special handling for CI - reinitialising the frontend device when the CI module is reset. Additionally the tda10021 needs to be set into a different transport stream mode when a CI module is present.
