Subject: [PATCH v2] KVM: x86: Remove unnecessary brackets in kvm_arch_dev_ioctl()
Date: Sat, 29 Feb 2020 10:52:12 +0800 [thread overview]
Message-ID: <20200229025212.156388-1-xiaoyao.li@intel.com> (raw)
In kvm_arch_dev_ioctl(), the brackets of case KVM_X86_GET_MCE_CAP_SUPPORTED
accidently encapsulates case KVM_GET_MSR_FEATURE_INDEX_LIST and case
KVM_GET_MSRS. It doesn't affect functionality but it's misleading.
Remove unnecessary brackets and opportunistically add a "break" in the
default path.
