Johan Hovold 7bcba557d5 Bluetooth: qca: fix firmware check error path
commit 40d442f969 upstream.

A recent commit fixed the code that parses the firmware files before
downloading them to the controller but introduced a memory leak in case
the sanity checks ever fail.

Make sure to free the firmware buffer before returning on errors.

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.
