Subject: [PATCH 4.4 16/18] ASoC: imx-spdif: Fix crash on suspend
Date: Mon, 4 May 2020 19:57:14 +0200 [thread overview]
Message-ID: <20200504165445.006367933@linuxfoundation.org> (raw)
In-Reply-To: <20200504165441.533160703@linuxfoundation.org>
From: Lars-Peter Clausen <lars@metafoo.de>
commit 9954859185c6e8359e71121037b627f1e294057d upstream.
When registering a ASoC card the driver data of the parent device is set to
point to the card. This driver data is used in the
snd_soc_suspend()/resume() callbacks.
The imx-spdif driver overwrites the driver data with custom data which
causes snd_soc_suspend() to crash. Since the custom driver is not used
anywhere simply deleting the line which sets the custom driver data fixes
the issue.
Fixes: 43ac946922b3 ("ASoC: imx-spdif: add snd_soc_pm_ops for spdif machine driver")
