Hi Vincent
While unregistering the hdmi-codec, the hdmi device list must be cleaned up. It avoids kernel page fault when registering again the hdmi-codec.

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 ?
