From 2474ed444b475614ef795523076be7cc8437ae00 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 19 Mar 2006 12:35:57 -0300 Subject: V4L/DVB (3582): Implement correct msp3400 input/output routing - implement VIDIOC_INT_S_AUDIO_ROUTING for msp3400 and tvaudio - use the new command in bttv, pvrusb2 and em28xx. - remove the now obsolete MSP_SET_MATRIX from msp3400 (yeah!) - remove the obsolete VIDIOC_S_AUDIO from msp3400.
