6.15-stable review patch. If anyone has any objections, please let me know.

commit 85a720f4337f0ddf1603c8b75a8f1ffbbe022ef9 upstream.
When sysfs_create_files() fails in wacom_initialize_remotes() the error is returned and the cleanup action will not have been registered yet.
As a result the kobject???s refcount is never dropped, so the kobject can never be freed leading to a reference leak.
Fix this by calling kobject_put() before returning.
