On systems where the UCSI PDOs are not supported, the UCSI driver is giving an error message. This can cause users to believe there is a HW issue with their system when in fact it is working as designed. Check if PDO_DETAILS are supported as a feature before attempting to access PDO. If not supported return that zero PDOs are available. Tested on Lenovo L14 G5 AMD and confirmed with Lenovo FW team that PDOs are not supported on this platform.

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.
