[PATCH 3.14 01/11] Revert "can: fix handling of unmodifiable configuration options fix"

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gre...@linuxfoundation.org>

This reverts commit 6f8f768a3586b6fbd50e249e7fe4f964a6994685 which was
bce271f255dae8335dc4d2ee2c4531e09cc67f5a upstream.

It was applied incorrectly, and isn't needed for 3.14-stable.
