OK, will do that for next version.

Regarding hda_eld.c, I guess I'll add struct hda_hdmi_ops to struct
hdmi_spec, then keep snd_hdmi_ati_get_eld() in hda_eld.c but make it
non-static, so I can assign the correct _get_eld in patch_hdmi.c?


P.S. I asked whether new callbacks should be added in the previous RFC
message, but I guess that was easy to overlook as the message was a bit
incoherent... :)
