Greg Kroah-Hartman f3674eb0fb ANDROID: fix up abi issue with struct snd_pcm_runtime 
A portion of the fix for CVE-2022-1048, commit 9cb6c40a6e ("ALSA: pcm:
Fix races among concurrent hw_params and hw_free calls") and
40f4cffbe1 ("ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and
mmap_lock"), caused an ABI break by adding a new field to struct
snd_pcm_runtime.  Because we have to keep this new addition, it is safe
to move it to the end of the structure because this is only ever created
by the sound core, and referenced as a pointer everywhere else.

This does require a .xml update also to handle the increased structure
size:

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.
