[ Upstream commit e12cd96e8e93044646fdf4b2c9a1de62cfa01e7c ] This modifies the AXI SPI Engine driver to use devm_spi_alloc_host() instead of spi_alloc_host() to simplify the code a bit. In addition to simplifying the error paths in the probe function, we can also remove spi_controller_get/put() calls in the remove function since devm_spi_alloc_host() sets a flag to no longer decrement the controller reference count in the spi_unregister_controller() function.

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.
