On ->setup, pm_runtime_enable() is only called if a valid IRQ was found, but on ->close(), pm_runtime_disable() is called unconditionally. Disablement of runtime PM is recorded in a counter, so every pm_runtime_disable() needs to be balanced. Fix it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
