Subject: [PATCH 1/2] KVM: VMX: Drop unprotected-by-braces variable declaration in case-statement
Date: Wed, 15 Mar 2023 12:11:27 -0700	[thread overview]
Message-ID: <20230315191128.1407655-2-seanjc@google.com> (raw)
In-Reply-To: <20230315191128.1407655-1-seanjc@google.com>

Remove the intermediate "guest_flush_l1d" boolean to fix a build error on
clang due to the variable being declared inside a case-statement without
curly braces to create a proper code block.

Fixes: c7ed946b95cb ("kvm: vmx: Add IA32_FLUSH_CMD guest support")
Reported-by: kernel test robot <lkp@intel.com>
