perf alias: Remove trailing newline when reading sysfs files
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'/
