David Arcari ecd052250b net: ethernet: aquantia: call set_irq_affinity_hint before free_irq 
When a network interface controlled by the aquantia ethernet driver is brought
down a warning is output in dmesg (see below).

The problem is that aq_pci_func_free_irqs() is calling free_irq() before it is
calling irq_set_affinity_hint().

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
