Shuai Xue d584acdf54 dmaengine: idxd: fix memory leak in error handling path of idxd_setup_wqs
commit 3fd2f4bc01 upstream.

Memory allocated for wqs is not freed if an error occurs during
idxd_setup_wqs(). To fix it, free the allocated memory in the reverse
order of allocation before exiting the function in case of an error.

Fixes: 7c5dd23e57 ("dmaengine: idxd: fix wq conf_dev 'struct device' lifetime")
Fixes: 700af3a0a2 ("dmaengine: idxd: add 'struct idxd_dev' as wrapper for conf_dev")
Fixes: de5819b994 ("dmaengine: idxd: track enabled workqueues in bitmap")
Fixes: b0325aefd3 ("dmaengine: idxd: add WQ operation cap restriction support")

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.
