commit 1c8093591d1e372d700fe65423e7315a8ecf721b upstream.
With current design, buffers and dma handles are not freed in case
of remote invocation failures returned from DSP. This could result
in buffer leakings and dma handle pointing to wrong memory in the
fastrpc kernel. Adding changes to clean buffers and dma handles
even when remote invocation to DSP returns failures.
Fixes: c68cfb718c8f ("misc: fastrpc: Add support for context Invoke method")

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.
