[ Upstream commit6c6871cdae] Mixing SPI slave/target handlers and SPI slave/target controllers using legacy and modern naming does not work well: there are now two different callbacks for aborting a slave/target operation, of which only one is populated, while spi_{slave,target}_abort() check and use only one, which may be the unpopulated one. Fix this by merging the slave/target abort callbacks into a single callback using a union, like is already done for the slave/target flags.

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.
