[ Upstream commitaea3877e24] On r8a7791/koelsch: m25p80 spi0.0: error -22 reading 9f m25p80: probe of spi0.0 failed with error -22 Apparently the logic in spi_mem_check_op() is wrong, rejecting the spi-mem operation if any buswidth is valid, instead of invalid.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
