From 154152aeea2c5ee4fd01b842257f5cb562234834 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Thu, 15 Sep 2011 16:44:47 -0500 Subject: drivers/video: fsl-diu-fb: clean up printk usage Remove debug printk messages (they don't help in debugging), replace printk(KERN_xxx with its pr_xxx or dev_xxx equivalent, and add a couple missing error messages.
