Gerhard Engleder 6847b00c3c misc: keba: Fix kernfs warning on module unload
Unloading the cp500 module leads to the following warning:

kernfs: can not remove 'eeprom', no directory
WARNING: CPU: 1 PID: 1610 at fs/kernfs/dir.c:1683 kernfs_remove_by_name_ns+0xb1/0xc0

The parent I2C device of the nvmem devices is freed before the nvmem
devices. The reference to the nvmem devices is put by devm after
cp500_remove(), but at this time the parent I2C device does not exist
anymore as the I2C controller and its devices have already been freed in
cp500_remove(). Thus, nvmem tries to remove an entry from an already
deleted directory.

Free nvmem devices before I2C controller auxiliary device.

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 reStructuredText 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.
