On unbind of the BCM2835 SPI driver, the SPI controller is disabled first and the DMA channels are terminated and torn down afterwards. This seems backwards: In the theoretical case that DMA is active, it might try to fill the SPI FIFOs even after the controller has been disabled. Reverse the order, thereby mirroring what's done on ->probe().

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.
