From 71d676345698b275955b2584803ae550972249e5 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 21 Jul 2011 17:46:41 -0300 Subject: [PATCH] [media] dvb: Add a new driver for az6007 Import the az6007 driver from Terratec H7 source, as-is. It won't compile or run, so latter patches are needed in order to fix it.
