From 853d9b18f1e861d37e9b271742329f8c1176eabe Mon Sep 17 00:00:00 2001 From: Levente Kurusa Date: Fri, 29 Nov 2013 21:28:48 +0100 Subject: [PATCH] x86, mce: Call put_device on device_register failure This patch adds a call to put_device() when the device_register() call has failed. This is required so that the last reference to the device is given up.
