Subject: [PATCH] [perf/core: Update sample_flags for raw_data in perf_output_sample
commit 838d9bb62d13 ("perf: Use sample_flags for raw_data")
added check for PERF_SAMPLE_RAW in sample_flags in
perf_prepare_sample(). But while copying the sample in memory,
the check for sample_flags is not added in perf_output_sample().
Fix adds the same in perf_output_sample as well.
Fixes: 838d9bb62d13 ("perf: Use sample_flags for raw_data")
