Myeonghun Pak 665a647b94 usb: sl811-hcd: disable controller wakeup on remove 
commit 4e8ba83ac4 upstream.

sl811h_probe() enables the HCD controller device as a wakeup source after
usb_add_hcd() succeeds, but sl811h_remove() removes the HCD and releases
the driver resources without disabling that wakeup source.

Disable controller wakeup after usb_remove_hcd() and before usb_put_hcd()
so the wakeup source object is detached while the controller device pointer
is still available.

This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

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.
