vfs: Remove second variable named error in __dentry_path
In commit 232d2d60aa5469bb097f55728f65146bd49c1d25 Author: Waiman Long <Waiman.Long@hp.com> Date: Mon Sep 9 12:18:13 2013 -0400 dcache: Translating dentry into pathname without taking rename_lock The __dentry_path locking was changed and the variable error was intended to be moved outside of the loop. Unfortunately the inner declaration of error was not removed. Resulting in a version of __dentry_path that will never return an error. Remove the problematic inner declaration of error and allow __dentry_path to return errors once again. Cc: stable@vger.kernel.org Cc: Waiman Long <Waiman.Long@hp.com> Signed-off-by: "Eric W.
