The comment says that we should not allow changes (to bits_per_word/speed_hz) while CS is active, and indeed the code below does fsl_spi_setup_transfer() when the ->cs_change of the previous spi_transfer was set (and for the very first transfer). So the sanity checking is a bit too strict - we can change it to follow the same logic as is used by the actual transfer loop.

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.
