commit 817b653160db9852d5a0498a31f047e18ce27e5b upstream.
On most systems request for IRQ 0 will fail, phylib will print an error message
and fall back to polling. To fix this set the phydev->irq to PHY_POLL if no IRQ
is available.
Fixes: cc89c323a30e ("lan78xx: Use irq_domain for phy interrupt from USB Int. EP")

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.
