Takashi and others, this patch is a follow-up to the earlier thread about hdac link management: https://mailman.alsa-project.org/pipermail/alsa-devel/2021-January/179715.html We have absolutely no calls from sound/pci/hda/ to hdaudio_ext.h before this patch, so I'm wondering if this is the right approach to take. It does seem to be the natural path forward and mimics what was done in e.g. hdac_hdmi. But we want to keep reusing driver code for all HDA implementations, so adding hdac-ext support to codec drivers seem like the best path. Br, Kai
