Subject: [PATCH AUTOSEL 5.15 25/26] ALSA: hda: intel-sdw-acpi: go through HDAS ACPI at max depth of 2
Date: Mon, 27 Dec 2021 14:03:26 -0500 [thread overview]
Message-ID: <20211227190327.1042326-25-sashal@kernel.org> (raw)
In-Reply-To: <20211227190327.1042326-1-sashal@kernel.org>
From: Libin Yang <libin.yang@intel.com>
[ Upstream commit 78ea40efb48e978756db2ce45fcfa55bac056b91 ]
In the HDAS ACPI scope, the SoundWire may not be the direct child of HDAS.
It needs to go through the ACPI table at max depth of 2 to find the
SoundWire device from HDAS.
