All irq_domain functions now accept fwnode instead of of_node. But many
PCI controllers still extract dev to of_node and then of_node to fwnode.
Instead, clean this up and simply use the dev_fwnode() helper to extract
fwnode directly from dev. Internally, it still does dev => of_node =>
fwnode steps, but it's now hidden from the users.
In the case of altera, this also removes an unused 'node' variable that is
only used when CONFIG_OF is enabled:
drivers/pci/controller/pcie-altera.c: In function 'altera_pcie_init_irq_domain':
drivers/pci/controller/pcie-altera.c:855:29: error: unused variable 'node' [-Werror=unused-variable]
855 | struct device_node *node = dev->of_node;

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 reStructuredText 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.
