commit 1571d67dc190e50c6c56e8f88cdc39f7cc53166e upstream. Rewrite the code to use irq_set_chained_handler_and_data() handler with chained_irq_enter() and chained_irq_exit() processing instead of using devm_request_irq(). advk_pcie_irq_handler() reads IRQ status bits and calls other functions based on which bits are set. These functions then read its own IRQ status bits and calls other aardvark functions based on these bits. Finally generic_handle_domain_irq() with translated linux IRQ numbers are called.

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.
