## Overview

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
