Franck LENORMAND 0070e73c9e firmware: imx: scu: Fix corruption of header
[ Upstream commit f5f27b79eab80de0287c243a22169e4876b08d5e ]

The header of the message to send can be changed if the
response is longer than the request:
 - 1st word, the header is sent
 - the remaining words of the message are sent
 - the response is received asynchronously during the
   execution of the loop, changing the size field in
   the header
 - the for loop test the termination condition using
   the corrupted header

It is the case for the API build_info which has just a
header as request but 3 words in response.

This issue is fixed storing the header locally instead of
using a pointer on it.

Fixes: edbee095fa (firmware: imx: add SCU firmware driver support)

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.
