+From f259d74e030faab15b95fb4bb56d7f424773c278 Mon Sep 17 00:00:00 2001
+From: Geoff Levand <geoffrey.levand@am.sony.com>
+Date: Tue, 6 Jan 2009 11:32:21 +0000
+Subject: [PATCH] mtd/ps3vram: Cleanup ps3vram driver messages
+
+Cleanup the ps3vram driver messages. Add a new struct device pointer
+variable dev to struct ps3vram_priv and use dev_dbg(), pr_dbg(), etc.
+where appropriate.
