From f259d74e030faab15b95fb4bb56d7f424773c278 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Tue, 6 Jan 2009 11:32:21 +0000 Subject: 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.
