From 668f06b9fb846ecedb73964ca5dd95ce441707be Mon Sep 17 00:00:00 2001 From: Emil Goode Date: Mon, 30 Jul 2012 14:42:51 -0700 Subject: pps: return PTR_ERR on error in device_create We should return PTR_ERR if the call to the device_create function fails. Without this patch we instead return the value from a successful call to cdev_add if the call to device_create fails.
