Subject: [PATCH 1/3] debugfs: update comment of debugfs_rename()
Since commit ff9fb72bc077 ("debugfs: return error values,
not NULL") changed return value of debugfs_rename() in
error cases from %NULL to %ERR_PTR(-ERROR), the comment
of debugfs_rename should also be updated so as not to
mislead readers.
