The driver core ignores the return value of struct device_driver::remove (because in general there is nothing that can be done about that). So add a warning when an spi driver returns an error. This simplifies the quest to make struct device_driver::remove return void. A consequent change would be to make struct spi_driver::remove return void, but I'm keeping this quest for later (or someone else).

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.
