spidev will make a big fuss if a device tree node binds a device by using "spidev" as the node's compatible property. However, the logic for this isn't looking for "spidev" in the compatible, but rather checking that the device is NOT compatible with spidev's list of devices. This causes a false positive if a device not named "rohm,dh2228fv", etc. binds to spidev, even if a means other than putting "spidev" in the device tree was used. E.g., the sysfs driver_override attribute.

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.
