Mark-YW.Chen 784e873af3 Bluetooth: btusb: fix memory leak in btusb_mtk_submit_wmt_recv_urb()
commit 60c6a63a3d3080a62f3e0e20084f58dbeff16748 upstream.

Driver should free `usb->setup_packet` to avoid the leak.

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.
