Subject: [PATCH 4.14 26/45] ALSA: hda - Force polling mode on CNL for fixing codec communication
Date: Thu, 20 Jun 2019 19:57:28 +0200 [thread overview]
Message-ID: <20190620174338.603309659@linuxfoundation.org> (raw)
In-Reply-To: <20190620174328.608036501@linuxfoundation.org>
[ Upstream commit fa763f1b2858752e6150ffff46886a1b7faffc82 ]
We observed the same issue as reported by commit a8d7bde23e7130686b7662
("ALSA: hda - Force polling mode on CFL for fixing codec communication")
We don't have a better solution. So apply the same workaround to CNL.
