The valid_mask member of the struct gpio_chip is unconditionally written by the GPIO core at driver registration. It should not be directly populated by the drivers. Hiding the valid_mask in struct gpio_device makes it clear it is not meant to be directly populated by drivers. This means drivers should not access it directly from the struct gpio_chip. The gpio-rcar checks the valid mask in set/get_multiple() operations. This is no longer needed [1]. Drop these checks. Additionally, the valid_mask is needed for enabling the GPIO inputs at probe time. Use the new valid_mask -getter function instead of accessing it directly from the struct gpio_chip.

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 reStructuredText 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.
