The current design of pca953x_irq_setup() is:
if (all conditions to support IRQ are met) {
lots of code to support IRQs, which goes to a serious indentation
level.
}
return 0;
It makes more sense to handle this like this:
if (!all conditions to support IRQ are met)
return 0;
handle IRQ support
This commit does just this change, reducing by one tab the indentation
level of the IRQ setup code. Thanks to this reduced indentation level,
we are less restricted by the 80-column limit, and we can have more
function arguments on the same line.

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.
