Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: rt712-sdca-dmic: fix uninitialized stream_config->type
stream_config is not initialized before being passed to sdw_stream_add_slave(). The type field may contain garbage and is later copied to stream->type by sdw_config_stream().
Zero-initialize stream_config so type defaults to SDW_STREAM_PCM.
While at it, use snd_sdw_params_to_config() helper instead of open-coding the same logic.
