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'/ Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: Hendrik Brueckner <brueckner@linux.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Link: http://lkml.kernel.org/r/20180615101105.47047-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
