Thank you about this patch.
I added original "hdmi_device_list" to this driver for DW-HDMI device purpose.
But, actually, 1) DW-HDMI binding method was exchanged, 2) I assumed it
will not be exchanged, and 3) this patch was accepted under such
(wrong) assumption.
Thus, this "hdmi_device_list" is no longer needed.
So, I'm planing to remove 9731f82d60166a19af6914f998092bbd1560f783
("ASoC: hdmi-codec: enable multi probe for same device")
and its related patch soon.
Can you agree about it ?
