When processing the netlink GET requests to get PHY info, the req_info.pdn
pointer is NULL when no PHY matches the requested parameters, such as when
the phy_index is invalid, or there's simply no PHY attached to the
interface.
Therefore, check the req_info.pdn pointer for NULL instead of
dereferencing it.

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.
