From da40c16a72f70329b599bb90a03bc23c8e0e7929 Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Wed, 20 Nov 2013 10:09:43 +0800 Subject: [PATCH] mtd: gpmi: change pr_err to dev_err There are pr_err and dev_err in the gpmi driver now. It makes people confused. This patch changes all the pr_err to dev_err except the one in the gpmi_reset_block(). We also remove the unnecessary print for OOM message.
