fbtft_remove_common() is only called with a non-NULL fb_info. (All callers are in remove callbacks and the matching probe callbacks set driver data accordingly.) So fbtft_remove_common() always returns zero. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of platform and spi remove callbacks is ignored anyway and not freeing resources in .remove() is a bad idea.

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.
