From 169e650069647325496e5a65408ff301874c8e01 Mon Sep 17 00:00:00 2001 From: Kui-Feng Lee Date: Sat, 3 Feb 2024 22:12:04 -0800 Subject: selftests/bpf: Suppress warning message of an unused variable. "r" is used to receive the return value of test_2 in bpf_testmod.c, but it is not actually used. So, we remove "r" and change the return type to "void".
