Commit 9e4555d1e54a ("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.
