Where was it called, actually? The call of patch_ops.init is found in several places: once in snd_hda_codec_build_controls() just before creating controls (which is the boot time init), and at resume, alc269_resume().
And, as already explained, we have to call this at resume, because it's not guaranteed that it's been already called in the case of hibernation.
thanks,
Takashi
