Commit a86ed2cfa13c5 ("ptp: Don't print an error if ptp_kvm is not supported") fixes the error message print on ARM platform by only concerning about the case that the error returned from kvm_arch_ptp_init() is not -EOPNOTSUPP. Although the ARM platform returns -EOPNOTSUPP if ptp_kvm is not supported while X86_64 platform returns -KVM_EOPNOTSUPP, both error codes share the same value 95. Actually kvm_arch_ptp_init() on X86_64 platform can return three kinds of errors (-KVM_ENOSYS, -KVM_EOPNOTSUPP and -KVM_EFAULT). The problem is that -KVM_EOPNOTSUPP is masked out and -KVM_EFAULT is ignored among them. This patch fixes this by returning them to ptp_kvm_init() respectively.
