openwrt-xburst/target/linux/ps3/patches-2.6.28/0010-mtd-ps3vram-Cleanup-ps3vram-driver-messages.patch

From f259d74e030faab15b95fb4bb56d7f424773c278 Mon Sep 17 00:00:00 2001
From: Geoff Levand <geoffrey.levand@am.sony.com>

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.
