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.
