[PATCH 3.19 15/75] ASoC: adav80x: Fix wrong value references for boolean kctl

From: Greg Kroah-Hartman
Date: Fri Apr 10 2015 - 09:24:04 EST


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

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

From: Takashi Iwai <tiwai@xxxxxxx>

commit 2bf4c1d483d911cda5dd385527194d23e5cea73d 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.
