Vincent Guittot 75c8f430d8 firmware: arm_scmi: Fix response size warning for OPTEE transport
Some protocols check the response size with the expected value but optee
shared memory doesn't return such size whereas it is available in the
optee output buffer.

As an example, the base protocol compares the response size with the
expected result when requesting the list of protocol which triggers a
warning with optee shared memory:

arm-scmi firmware:scmi0: Malformed reply - real_sz:116  calc_sz:4  (loop_num_ret:4)

Save the output buffer length and use it when fetching the answer.

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.

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.
