Subject: [PATCH v5 2/2] ALSA: hda - identify when audio is provided by a video driver
Date: Sat, 30 Apr 2022 21:04:55 +0100	[thread overview]
Message-ID: <4a0f0e351941201d00b2cd8e2157d3b0181dc19e.1651348913.git.mchehab@kernel.org> (raw)
In-Reply-To: <cover.1651348913.git.mchehab@kernel.org>

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.
