sound/hda: Module loading problem of controller and codec

Hi Takashi, The following commit only gives a warning in menuconfig: "Set to Y if you want auto-loading the codec driver"

d8f66c71d547 ("ALSA: hda - Add warning texts when codec driver Kconfig doesn't match") 78e34f34ac27 ("ALSA: hda - remove PCI dependency in Kconfig")

The problem with module loading is because when SND_HDA=y, sound/pci/hda/hda_bind.c is not compiled as a module.There is a “#ifdef MODULE“ in the codec_bind_module function in this file. Why can't it be deleted directly?Or am I missing something?
