For a direct attached device, attached_phy contains the local phy id.
For a device behind an expander, attached_phy contains the remote phy
id, not the local phy id.
The pm8001_ha->phy array only contains the phys of the HBA. It does not
contain the phys of the expander.
Thus, you cannot use attached_phy to index the pm8001_ha->phy array,
without first verifying that the device is directly attached.
Use the pm80xx_get_local_phy_id() helper to make sure that we use the
local phy id to index the array, regardless if the device is directly
attached or not.
Fixes: 869ddbdcae ("scsi: pm80xx: corrected SATA abort handling sequence.")

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.
