From c5317b17f6ca74531a6c707873dc5d25f1877ac3 Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sat, 9 Feb 2008 19:47:07 -0300 Subject: [PATCH] V4L/DVB (7692): pvrusb2-dvb: Further clean up dvb init/tear-down Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's really private to the pvrusb2-dvb module and nothing outside of the dvb implementation should care about it. Creation / destruction of the pvr2_dvb_adapter instance is now contained entirely within pvrusb2-dvb.c.
