Descriptions

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.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soundwire: stream: corrige la pérdida de memoria en la ruta de error de configuración de stream Cuando falla la configuración de stream, el tiempo de ejecución maestro liberará todo el tiempo de ejecución esclavo en Slave_rt_list, pero el tiempo de ejecución esclavo no se agrega a la lista. en este momento. Este parche libera el tiempo de ejecución esclavo en la ruta del error de configuración para corregir la pérdida de memoria.
