We already have an array named "parents" so instead of letting one point to the other, simply allocate a dynamic array to hold the parents, just one if desired and drop the number of members in gpio_irq_chip by 1. Rename gpiochip to gc in the process. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
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.
