When requesting an interrupt, we correctly call into the runtime PM framework to guarantee that the underlying interrupt controller is up and running. However, we fail to do so for chained interrupt controllers, as the mux interrupt is not requested along the same path. Augment __irq_do_set_handler() to call into the runtime PM code in this case, making sure the PM flow is the same for all interrupts.

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.
