edac: core fix added newline to sysfs dimm labels
The channel DIMM label does not seem to be used much in the edac code. However, where it is used (in the core code), it is assumed to not have a newline embedded. This leaves the sysfs file newline free which looks funny when cat'ing it. Here we just add the trailing newline to the sysfs chX_dimm_label output... [Doug Thompson note: the DIMM label is one of the primary uses of EDAC. User space daemon scripts, edac-utils@sourceforge, populate the DIMM label fields, via /sys/devices/system/edac attributes, with the silk screen labels of the motherboard in use. dmidecode access BIOS tables, but BIOS tables are well known to be incorrect and useless in these respects. edac-utils will strip off any newlines before its use of the output, when displaying DIMM slot silk screen labels.
