Returning an error in .remove() doesn't prevent a driver from being unloaded. On unbind this only results in an error message, but the device is remove anyhow. I guess the author's idea of just returning -EPERM in .remove() was to prevent unbinding a device. To achieve that set the suppress_bind_attrs driver property and drop the useless .remove callback. This is a preparation for making platform remove callbacks return void.

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.
