commitd8a46bc4e1upstream. On receiving last buffer driver puts MFC to MFCINST_FINISHING state which in turn skips transferring of frame from SRC to REF queue. This causes driver to stop MFC encoding and last frame is lost. This patch guarantees safe handling of frames during MFCINST_FINISHING and correct clearing of workbit to avoid early stopping of encoding.

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.
