Subject: [PATCH 3.4 112/172] ASoC: wm2000: Fix wrong value references for boolean kctl

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

3.4.108-rc1 review patch.  If anyone has any objections, please let me know.

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


commit 00a14c2968e3d55817e0fa35c78106ca840537bf 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.
