The driver must have a .remove function, because the platform device it is binding against can appear and disappear.

Thank you for your feedback OK, I will add it

This driver uses platform_device_register_full() and calls hdmi-codec driver. This driver itself doesn't register sound card, like dw-hdmi-ahb-audio.c Then, what does .remove should do in this case ?

Remove the platform device that was created by platform_device_register_full().
