Subject: r820t tuner oops on kernel 3.10.8
Date: Tue, 20 Aug 2013 23:03:02 +0200	[thread overview]
Message-ID: <5213D986.4070204@xutrox.com> (raw)

Hello,

Can commit 4aab0398e003ac2effae98ba66a012ed715967ba be added to linux
stable?

Without this patch I get the following error (after unplugging and
reconnecting the dvb-t device):
