Subject: [PATCH v2 1/4] kernfs: add dummy implementation of
 kernfs_path_from_node()

>From 17d6dfb3afa88253bf1ceee2d4a5e461970fc593 Mon Sep 17 00:00:00 2001

The dummy version of kernfs_path_from_node() was missing.  This
currently doesn't break anything.  Let's add it for consistency and to
ease adding wrappers around it.

v2: Removed stray ';' which was causing build failures.
