The first two patches change snd_soc_card_get_kcontrol() to use the
core snd_ctl_find_id_mixer() functionality instead of open-coding its
own list walk.

The last patch adds a KUnit test for this, which was tested on the
original and modified code.

Richard Fitzgerald (3):
  ALSA: control: Introduce snd_ctl_find_id_mixer_locked()
  ASoC: soc-card: Use snd_ctl_find_id_mixer() instead of open-coding
  ASoC: soc-card: Add KUnit test case for snd_soc_card_get_kcontrol
