Subject: [PATCH v6 4/4] ALSA: hda - identify when audio is provided by a video driver
Date: Mon, 9 May 2022 18:23:39 +0200 [thread overview]
Message-ID: <f53f8a9d04b39a6843f19fe3069d1be7a9713aae.1652113087.git.mchehab@kernel.org> (raw)
In-Reply-To: <cover.1652113087.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.
