From 62af2ba09181e8b6c7db6fc777770860ae7674b5 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 3 Nov 2007 19:05:07 +0100 Subject: em28xx: add support for vgear pockettv From: Sascha Sommer attached patch adds support for the vgear pockettv. It seems to require a write to another register for audio to work. I checked my old cinergydrv and we did the same register write there. I therefore enabled it for all em2800 based devices.
