Subject[PATCH] i7core_edac, Fix panic when accessing sysfs files
Date
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().
