[PATCH] ASoC: tegra: Fix -Wuninitialized in tegra210_amx_platform_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Clang warns (or errors with CONFIG_WERROR=y):

  sound/soc/tegra/tegra210_amx.c:553:10: error: variable 'soc_data' is uninitialized when used here [-Werror,-Wuninitialized]
    553 |                                             soc_data->regmap_conf);
        |                                             ^~~~~~~~

A refactoring removed the initialization of this variable but its use
was not updated. Use the soc_data value in the amx variable to resolve
the warning and remove the soc_data variable, as it is now entirely
unused.

Closes: https://github.com/ClangBuiltLinux/linux/issues/1943
Fixes: 9958d85968ed ("ASoC: Use device_get_match_data()")
