Linux kernel source tree

There's no need to overwrite fwf_name with a kstrdup() of the cs_dsp part name. It is trivial to select either fwf_name or cs_dsp.part as the string to use when building the filename in wm_adsp_request_firmware_file(). This leaves fwf_name entirely owned by the codec driver. It also avoids problems with freeing the pointer. With the original code fwf_name was either a pointer owned by the codec driver, or a kstrdup() created by wm_adsp. This meant wm_adsp must free it if it set it, but not if the codec driver set it. The code was handling this by using devm_kstrdup(). But there is no absolute requirement that wm_adsp_common_init() must be called from probe(), so this was a pseudo-memory leak - each new call to wm_adsp_common_init() would allocate another block of memory but these would only be freed if the owning codec driver was removed.

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.
