Please use this commit message for your next version:
EDAC/mc_sysfs: Add missing newlines when printing {max,dimm}_location
Reading those sysfs entries gives:
[root@localhost /]# cat /sys/devices/system/edac/mc/mc0/max_location
memory 3 [root@localhost /]# cat /sys/devices/system/edac/mc/mc0/dimm0/dimm_location
memory 0 [root@localhost /]#
Add newlines after the value it prints for better readability.

No size checking here?
