[alsa-devel] [PATCH v2] ASoC: rt5677: Fix initialization of rt5677_of_match.data

[Matthias Kaehlcke]

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 },
                                      ^~~~~~

Fixes: ddc9e69b9dc2 ("ASoC: rt5677: Hide platform data in the module sources")
