From 5da80ee8d863c32719e3431054e26a0ef1a02a51 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 7 Sep 2012 17:50:58 -0700 Subject: [PATCH] staging: comedi: me4000: convert printk's to dev_printk's A lot of the messages produced by this driver are just noise and need to be removed. For now just convert them all to dev_printk's.
