Dan Carpenter 1bae8f424c staging: greybus: use after free in gb_audio_manager_remove_all() 
commit b7db58105b upstream.

When we call kobject_put() and it's the last reference to the kobject
then it calls gb_audio_module_release() and frees module.  We dereference
"module" on the next line which is a use after free.

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
