Subject: [PATCH] perf parse: Add missing newline to pr_debug message in evsel__compute_group_pmu_name()
The newline is missing for pr_debug message in
evsel__compute_group_pmu_name(), fix it.
Before:
# perf --debug verbose=2 record -e cpu-clock true
<SNIP>
No PMU found for 'cycles:u'No PMU found for 'instructions:u'------------------------------------------------------------
perf_event_attr:
type 1
size 136
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|PERIOD
read_format ID|LOST

enable_on_exec 1
task 1
sample_id_all 1
