Returning an error code in the remove callback yields to an error message remove callback returned a non-zero value. This will be ignored. After that the device is removed anyhow. Improve the error message to at least say what the actual problem is. While touching that code, convert the driver to the .remove_new() callback which returns no value with the same effect as returning zero in a .remove() callback. As the return value is ignored by the core the only effect of this patch is to improve the error message. (And the motivating effect is that there is one less driver using .remove().)

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.
