Ben Hutchings 564e1986b0 scsi: aacraid: Fix double-free on probe failure
[ Upstream commit 919ddf8336f0b84c0453bac583808c9f165a85c2 ]

aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.

After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.

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.
