Subject: ASoC: dapm: Fix ctl value accesses in a wrong type

From: Takashi Iwai <[email protected]>

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')
