BIT macro is being used to get mask for gpio's pin which is retrieved using 'hwirq' from struct irq_data. The problem here is that 'hwirq' can be as large as 95, and 1UL << 95 is unlikely to work well. Instead of using BIT macro use a new PIN_MASK macro which takes into account pin and WIDTH of the bank in order to make a proper mask for the gpio pin. Also 'd->hwirq' has been replaced by 'pin' in some places because there was a 'pin' variable in changed functions with the proper value. This improves readability.

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.
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.
