Subject: perf session: Add missing sample flush for piped events
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8c16b649606ff9f6d742ad6f71c76fc0ee996c8e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

perf session: Add missing sample flush for piped events

Piped events can be sorted so a final flush is needed.

Add that and remove a redundant 'err = 0'.
