Qasim Ijaz ee49c0e99a HID: wacom: fix memory leak on sysfs attribute creation failure
commit 1a19ae437ca5d5c7d9ec2678946fb339b1c706bf upstream.

When sysfs_create_files() fails during wacom_initialize_remotes() the
fifo buffer is not freed leading to a memory leak.

Fix this by calling kfifo_free() before returning.

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.
