Subject: [PATCH] selftests: kvm: replace ternary operator with min()
Date: Wed, 11 May 2022 20:05:55 +0800	[thread overview]
Message-ID: <20220511120621.36956-1-guozhengkui@vivo.com> (raw)

Fix the following coccicheck warnings:

tools/testing/selftests/kvm/lib/s390x/ucall.c:25:15-17: WARNING
opportunity for min()
tools/testing/selftests/kvm/lib/x86_64/ucall.c:27:15-17: WARNING
opportunity for min()
tools/testing/selftests/kvm/lib/riscv/ucall.c:56:15-17: WARNING
opportunity for min()
tools/testing/selftests/kvm/lib/aarch64/ucall.c:82:15-17: WARNING
opportunity for min()
tools/testing/selftests/kvm/lib/aarch64/ucall.c:55:20-21: WARNING
opportunity for min()

min() is defined in tools/include/linux/kernel.h.
