The referenced commit added in .config_intr() the part of code which upon
configuration of the IRQ state it also clears up any pending IRQ. If
there were actually pending IRQs, a read on the IRQ status register will
return something non zero. This should not result in the callback
returning an error.
Fix this by returning an error only when the result of the
phy_read_mmd() is negative.

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.
