Joe Hattori 57797497a6 usb: chipidea: ci_hdrc_imx: decrement device's refcount in .remove() and in the error path of .probe()
commit 74adad5003 upstream.

Current implementation of ci_hdrc_imx_driver does not decrement the
refcount of the device obtained in usbmisc_get_init_data(). Add a
put_device() call in .remove() and in .probe() before returning an
error.

This bug was found by an experimental static analysis tool that I am
developing.

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 reStructuredText 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.
