[ Upstream commit445110941e] led_put() is used to "undo" a successful of_led_get() call, of_led_get() uses class_find_device_by_of_node() which returns a reference to the device which must be free-ed with put_device() when the caller is done with it. Add a put_device() call to led_put() to free the reference returned by class_find_device_by_of_node(). And also add a put_device() in the error-exit case of try_module_get() failing.

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.
