[PATCH 4.18 114/197] ASoC: rt5677: Fix initialization of rt5677_of_match.data

From: Greg Kroah-Hartman
Date: Thu Sep 13 2018 - 10:02:11 EST


4.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>

[ Upstream commit f861e3e28a3016a2064d9f600eaa92a530b732b4 ]

The driver expects to find the device id in rt5677_of_match.data, however
it is currently assigned to rt5677_of_match.type. Fix this.

The problem was found with the help of clang:
sound/soc/codecs/rt5677.c:5010:36: warning: expression which evaluates to
zero treated as a null pointer constant of type 'const void *'
[-Wnon-literal-null-conversion]
{ .compatible = "realtek,rt5677", RT5677 },
^~~~~~
