We deprecated open coding of the transfer queue back in 2017 so it's high time we finished up converting drivers to use the standard message queue code. The mpc52xx-psc driver is fairly straightforward so convert to use transfer_one_message(), it looks like the driver would be a good fit for transfer_one() with a little bit of updating but this smaller change seems safer. The driver seems like a good candidate for transfer_one() but the chip select function is actually doing rather more than just updating the chip select and both transfer_one() and transfer_one_message() are current APIs so leave that refactoring for another day, ideally by someone with the hardware.

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.
