From 6a0bfff44e4aa4ee1721b3daa004d2039576c70d Mon Sep 17 00:00:00 2001 From: Tim Pepper Date: Mon, 27 Oct 2008 12:18:36 +0800 Subject: Blackfin arch: handle case of d_path() returning error in decode_address() d_path() can return an error. Most of its callers do something or other to make up something sane in that case. Do similar for blackfin's decode_address() call to d_path().
