From 43f8e28916e96bf71c01591711168a1eaa58d8e3 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 11 Nov 2013 11:02:52 -0300 Subject: [PATCH] media: wm8775: fix broken audio routing commit 3af41a337a5b270de3e65466a07f106ad97ad0c6 upstream. Commit 5aa9ae5ed5d449a85fbf7aac3d1fdc241c542a79 inverted the mute control state test in s_routing which caused the audio routing to fail. This broke ivtv support for the Hauppauge video/audio input bracket (which adds additional video and audio inputs) all the way back in kernel 2.6.36. This fix fixes the condition and it also removes a nonsense check on the balance control.
