The driver core ignores the return value of a bus' remove callback. However a driver returning an error code is a hint that there is a problem, probably a driver author who expects that returning e.g. -EBUSY has any effect. The right thing to do would be to make struct platform_driver::remove() return void. With the immense number of platform drivers this is however a big quest and I hope to prevent at least a few new drivers that return an error code here.

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.
