From: Thomas Richter <tmricht@linux.ibm.com>
Remove a trailing newline when reading sysfs file contents such as /sys/devices/cpum_cf/events/TX_NC_TEND. This shows when verbose option -v is used.
Output before:
tx_nc_tend -> 'cpum_cf'/'event=0x008d '/
Output after:
tx_nc_tend -> 'cpum_cf'/'event=0x8d'/
