[Intel-gfx] [PATCH v3 2/2] ALSA: hda - identify when audio is provided by a video driver

[Mauro Carvalho Chehab]

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.
