Subject: [PATCH 1/5] tests/qtest/ipmi-kcs: Fix assert side-effect
Date: Wed, 2 Sep 2020 10:07:57 +0200 [thread overview]
Message-ID: <20200902080801.160652-2-philmd@redhat.com> (raw)
In-Reply-To: <20200902080801.160652-1-philmd@redhat.com>
Fix assert side-effect reported by Coverity:
/qemu/tests/qtest/ipmi-kcs-test.c: 84 in kcs_wait_obf()
83 while (IPMI_KCS_CMDREG_GET_OBF() == 0) {
>>> CID 1432368: Incorrect expression (ASSERT_SIDE_EFFECT)
>>> Argument "--count" of g_assert() has a side effect. The containing function might work differently in a non-debug build.
