Davidlohr Bueso c43e036d6f cxl/mbox: Use new return_code handling
Use the global cxl_mbox_cmd_rc table to improve debug messaging
in __cxl_pci_mbox_send_cmd() and allow cxl_mbox_send_cmd()
to map to proper kernel style errno codes - this patch
continues to use -ENXIO only so no change in semantics.

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.
