#1357463 — [PATCH 4.4 18/50] ASoC: dapm: Fix ctl value accesses in a wrong type

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

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

From: Takashi Iwai <tiwai@suse.de>

commit 741338f99f16dc24d2d01ac777b0798ae9d10a90 upstream.

snd_soc_dapm_dai_link_get() and _put() access the associated ctl
values as value.integer.value[].  However, this is an enum ctl, and it
has to be accessed via value.enumerated.item[].  The former is long
while the latter is unsigned int, so they don't align.

Fixes: c66150824b8a ('ASoC: dapm: add code to configure dai link parameters')
