There are no more users of the deprecated is_dma_mapped in struct spi_message so it can be removed. References in documentation and comments are also removed. A few similar checks if xfer->tx_dma or xfer->rx_dma are not NULL are also removed since these are now guaranteed to be NULL because they were previously set only if is_dma_mapped was true.

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 reStructuredText 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.
