Remove UNIQUE_WWID_IN_REPORT_PHYS_LUN PQI feature. This feature was originally added to solve a problem with NVMe drives, but this problem has since been solved a different way, so this PQI feature is no longer required for any type of drive. The kernel was not creating symbolic links in sysfs between SATA drives and their enclosure. The driver was enabling the UNIQUE_WWID_IN_REPORT_PHYS_LUN PQI feature, which causes the FW to return a WWID for SATA drives that is derived from a unique ID read from the SATA drive itself. The driver was exposing this WWID as the drive's SAS address. However, because this SAS address does not match the SAS address returned by an enclosure's SES Page 0xA data, the Linux kernel was not able to match a SATA drive with its enclosure.

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.
