[ Upstream commit 0cf253eed5d2bdf7bb3152457b38f39b012955f7 ] The driver currently leaves GPIO IRQs unmasked even when the GPIO IRQ client has released the GPIO IRQ. This allows the HW to raise IRQs, and SW to process them, after shutdown. Fix this by masking the IRQ when it's shut down. This is usually taken care of by the irqchip core, but since this driver has a custom irq_shutdown implementation, it must do this explicitly itself.

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.
