A change to the defconfig would be applied by the RPi maintainers, and a
change to drivers/spi by the SPI maintainers. Those need to be in
different patches.

Error checking?

The return value needs to be error-checked, so that deferred probe can
work, and so other kinds of errors can be detected. Wasn't this correct
in a previous patch version?
Note that I didn't review any code besides probe(), remove() and the
driver boiler-plate that refers to those functions.
