Subject: ASoC: dapm: Fix ctl value accesses in a wrong type
From: Takashi Iwai <tiwai@xxxxxxx>
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')
