Since this callback is specific to HDMI/DP, a more specific name would be better. Otherwise this sounds like a generic hotplug handler.
Or, we may make it really generic, e.g. something like void (*hotplug_notify)(struct hdac_device *, int event_type, const void *data);
and call it with a specific event_type value codec->hotplug_notify(codec, HDAC_NOTIFY_I915_DP, hotplug_info);
