ASoC: SOF: imx: imx8: Bar index is only valid for IRAM and SRAM types
i.MX8 only uses SOF_FW_BLK_TYPE_IRAM (1) and SOF_FW_BLK_TYPE_SRAM (3)
bars, everything else is left as 0 in sdev->bar[] array.

If a broken or purposefully crafted firmware image is loaded with other
types of FW_BLK_TYPE then a kernel crash can be triggered.

Make sure that only IRAM/SRAM type is converted to bar index.

Fixes: 202acc565a ("ASoC: SOF: imx: Add i.MX8 HW 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.
