Vulnerability Details : CVE-2021-47020
In the Linux kernel, the following vulnerability has been resolved:
soundwire: stream: fix memory leak in stream config error path
When stream config is failed, master runtime will release all
slave runtime in the slave_rt_list, but slave runtime is not
added to the list at this time. This patch frees slave runtime
in the config error path to fix the memory leak.
