[PATCH v2 05/13] perf parse-events: Avoid regrouped warning for wild card events
From: Ian Rogers
Date: Tue Jun 27 2023 - 14:11:51 EST
There is logic to avoid printing the regrouping warning for wild card
PMUs, this logic also needs to apply for wild card events.
Before:
```
$ perf stat -e '{data_read,data_write}' -a sleep 1
WARNING: events were regrouped to match PMUs
Performance counter stats for 'system wide':
2,979.16 MiB data_read
410.26 MiB data_write
1.001541923 seconds time elapsed
```
After:
```
$ perf stat -e '{data_read,data_write}' -a sleep 1
Performance counter stats for 'system wide':
2,975.94 MiB data_read
432.05 MiB data_write
1.001119499 seconds time elapsed
```
