From 5e7aa97c7acf171275ac02a8bb018c31b8918d13 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Tue, 3 Dec 2024 18:09:55 +0100 Subject: [PATCH] ptp: kvm: x86: Return EOPNOTSUPP instead of ENODEV from kvm_arch_ptp_init() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
