From ab30f3b84e41060d3e038b977b5fd2a3ff045768 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 11 Apr 2008 08:29:44 -0300 Subject: cx88/saa7134: Fix: avoid OOPS on module unload From: Mauro Carvalho Chehab If frontend is not attached, both cx88-dvb and saa7134-dvb don't register DVB. However, dvb unregister were inconditionally called. Due to that, an OOPS is generated.
