While the current code is perfectly fine (because we verify that the device is directly attached before using attached_phy to index the pm8001_ha->phy array), let's use the pm80xx_get_local_phy_id() helper anyway, to reduce the chance that someone will copy paste this pattern to other parts of the driver. Note that in this specific case, we still need to keep the check that the device is not behind an expander, because we do not want to clear attached_phy of the expander if a device behind the expander disappears (as that would disable all the other devices behind the expander). However, if it is the expander itself that disappears, attached_phy will be cleared, just like it would for any other directly attached device.

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.
