PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the
irq_set_chained_handler_and_data() results in warnings from the GPIOLIB
(see 461c1a7d47 ("gpiolib: override irq_enable/disable"))
as in this path the IRQ resources are not allocated (and thus the
corresponding GPIO is not marked as used for the IRQ. Use request_irq so
that the IRQ resources are proprely setup.

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.
