Subject: [PATCH -next] x86/kvm: fix a missing-prototypes "vmread_error"
Date: Thu, 2 Apr 2020 11:39:55 -0400 [thread overview]
Message-ID: <20200402153955.1695-1-cai@lca.pw> (raw)
The commit 842f4be95899 ("KVM: VMX: Add a trampoline to fix VMREAD error
handling") removed the declaration of vmread_error() causes a W=1 build
failure with KVM_WERROR=y. Fix it by adding it back.
arch/x86/kvm/vmx/vmx.c:359:17: error: no previous prototype for 'vmread_error' [-Werror=missing-prototypes]
asmlinkage void vmread_error(unsigned long field, bool fault)
