Subject: [PATCH 3.10 08/23] ASoC: wm8904: Fix wrong value references for boolean kctl

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

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

From: Takashi Iwai <tiwai@...e.de>

commit eaddf6fd959074f6a6e71deffe079c71eef35da6 upstream.

The correct values referred by a boolean control are
value.integer.value[], not value.enumerated.item[].
The former is long while the latter is int, so it's even incompatible
on 64bit architectures.
