The error path of soc_new_pcm_runtime() invokes soc_free_pcm_runtime() that may cause a few problems. First off, it calls list_del() for rtd->list that may not be initialized. Similarly, snd_soc_pcm_component_free() traverses over the component list that may not be initialized, either. Such access to the uninitialized list head would lead to either a BUG_ON() or a memory corruption. This patch fixes the access to uninitialized list heads by initializing the list heads properly at the beginning before those error paths.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
