Description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: max98363: 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.
