On some devices, the hda driver needs to hook into a video driver, in order to be able to properly access the audio hardware and/or the power management function.
That's the case of several snd_hda_intel devices that depends on i915 driver.
Ensure that a proper reference between the snd-hda driver needing such binding is shown at /proc/modules, in order to allow userspace to know about such binding.
