After changing the valid_mask for the struct gpio_chip to detect the need and presence of a valid mask with the presence of a .init_valid_mask() callback to fill it in, we augment the gpio_irq_chip to use the same logic. Switch all driver using the gpio_irq_chio valid_mask over to this new method. This makes sure the valid_mask for the gpio_irq_chip gets filled in when we add the gpio_chip, which makes it a little easier to switch over drivers using the old way of setting up gpio_irq_chip over to the new method of passing the gpio_irq_chip along with the gpio_chip. (See drivers/gpio/TODO for details.)

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.
