To avoid such issue, split the dai array into HDMI and non HDMI array and register them conditionally: for HDMI hdev only register the dais needed for HDMI for non HDMI hdev do not register the HDMI dais.

Hi,

Changes since v1:

• Drop the patch for patch_hdmi to export a funtion to match the device
• Use the struct hdac_hda_priv.need_display_power boolean as indication that the device is a HDMI/DP audio codec

LGTM.
