Commit9e4555d1e5("gpiolib: add support for scope-based management to gpio_device") sought to add scope-based gpio_device refcounting, but erroneously forgot a negation of IS_ERR_OR_NULL(). As a result, gpio_device_put() is not called if the gpio_device pointer is valid (meaning the ref is leaked), but only called if the pointer is NULL or an ERR_PTR(). While at it drop a superfluous trailing semicolon.

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.
