Subject: [PATCH] ASoC: intel: skl_hda_dsp_common: create HDMI jack kctl
Git-commit: 0e4cc44f5066b22938f384cd57db99d66311de90
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518
This patch call snd_jack_add_new_kctl() to create the HDMI jack kctls.
Userspace needs these kctls to detect the hdmi monitor hotplug.
In /usr/share/alsa/ucm, the config file needs to assign a jack kctl to
"JackControl" to let PA get the jack hotplug status.
