Vishakha Channapattan 4f608fbce5 scsi: pm80xx: Log SATA IOMB completion status on failure
Added a log message in SATA completion path to capture the status of failed
command. If the status does not match any expected status, another message
will be logged.

On IO failure with known status, the log message will be:

  [ 1712.951735] pm80xx0:: mpi_sata_completion 2269: IO failed device_id 16385 status 0x1 tag XX

If the firmware returns unexpected status, a message of the following
format will be logged:

  [ 1712.951735] pm80xx0:: mpi_sata_completion XXXX: Unknown status device_id XXXXX status 0xX tag XX

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.
