From 42709efb3a47524c6252e1bdc85e205f7bc356fb Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Tue, 16 Oct 2012 09:02:27 -0400 Subject: [PATCH] i7core_edac: fix panic when accessing sysfs files The i7core_edac addrmatch_dev and chancounts_dev have sysfs files associated with them. The sysfs files, however, are coded so that the parent device is is the mci device. This is incorrect and the mci struct should be obtained through the addrmatch_dev and chancounts_dev device's private data field which is populated in i7core_create_sysfs_devices().
