[ Upstream commit95590a6286] of_find_device_by_node takes a reference to the struct device when it finds a match via get_device. but it fails to put_device in at91_pm_config_ws, for_each_matching_node_and_match will get and put the node properly, there is no need to call the of_put_node. Therefore, just call put_device instead of of_node_put in at91_pm_config_ws.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
