commit 514ccc194971d0649e4e7ec8a9b3a6e33561d7bf upstream.
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) ^~~~~~~~~~~~
