[PATCH 5.8 177/186] perf record: Correct the help info of option "--no-bpf-event"

From: Greg Kroah-Hartman

From: Wei Li <liwei391@xxxxxxxxxx>

commit a060c1f12b525ba828f871eff3127dabf8daa1e6 upstream.

The help info of option "--no-bpf-event" is wrongly described as "record
bpf events", correct it.

Committer testing:

$ perf record -h bpf

Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]

--clang-opt <clang options>
options passed to clang when compiling BPF scriptlets
--clang-path <clang path>
clang binary to use for compiling BPF scriptlets
--no-bpf-event do not record bpf events


Fixes: 71184c6ab7e6 ("perf record: Replace option --bpf-event with --no-bpf-event")
