Subject: [PATCH 4.1 083/267] ASoC: tas2552: Fix kernel crash caused by wrong kcontrol entry

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Ujfalusi <peter.ujfalusi@...com>

commit 1cf0f44811b754b64283b11ef0e60cb0de07b29c upstream.

SOC_DAPM_SINGLE("Playback AMP", ..) should not be under kcontrols. It
causes kernel crash (NULL pointer) when the mixers are listed.
