[ Upstream commit 5e7aa97c7acf171275ac02a8bb018c31b8918d13 ]
The caller, ptp_kvm_init(), emits a warning if kvm_arch_ptp_init() exits with any error which is not EOPNOTSUPP:
"fail to initialize ptp_kvm"
Replace ENODEV with EOPNOTSUPP to avoid this spurious warning, aligning with the ARM implementation.
