selftests: kvm: move declaration at the beginning of main()
Placing a declaration of evt_reset is pedantically invalid according to the C standard. While GCC does not really care and only warns with -Wpedantic, clang ignores the declaration altogether with an error: x86_64/xen_shinfo_test.c:965:2: error: expected expression struct kvm_xen_hvm_attr evt_reset = { ^ x86_64/xen_shinfo_test.c:969:38: error: use of undeclared identifier evt_reset vm_ioctl(vm, KVM_XEN_HVM_SET_ATTR, &evt_reset); ^ Reported-by: Yu Zhang <yu.c.zhang@linux.intel.com> Reported-by: Sean Christopherson <seanjc@google.com> Fixes: a79b53aaaab5 ("KVM: x86: fix deadlock for KVM_XEN_EVTCHN_RESET", 2022-12-28) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
