Subject: [PATCH 3.4 110/172] ASoC: ak4641: 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 08641d9b7bf915144a57a736b42642e13eb1167f 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.
