Arnd Bergmann 83e25ef2b8 ASoC: Intel: mrfld: fix uninitialized variable access 
[ Upstream commit 1539c7f23f ]

Randconfig testing revealed a very old bug, with gcc-8:

sound/soc/intel/atom/sst/sst_loader.c: In function 'sst_load_fw':
sound/soc/intel/atom/sst/sst_loader.c:357:5: error: 'fw' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  if (fw == NULL) {
     ^
sound/soc/intel/atom/sst/sst_loader.c:354:25: note: 'fw' was declared here
  const struct firmware *fw;

We must check the return code of request_firmware() before we look at the
pointer result that may be uninitialized when the function fails.

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.
