Currently, the calling of mutex_destroy() is ignored on error handling code path. It is safe for now, since mutex_destroy() actually does nothing in non-debug builds. But the mutex_destroy() is used to mark the mutex uninitialized on debug builds, and any subsequent use of the mutex is forbidden. It also could lead to problems if mutex_destroy() gets extended, add missing mutex_destroy() to eliminate potential concerns.

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 reStructuredText 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.
