Subject: [PATCH bpf-next 2/5] selftests/bpf: fix checkpatch error on empty function parameter
Fix checkpatch error: "ERROR: Bad function definition - void foo()
should probably be void foo(void)". Most replacements are done by
the following command:
sed -i 's#\([a-z]\)()$#\1(void)#g' testing/selftests/bpf/benchs/*.c
