From a86ed2cfa13c5175eb082c50a644f6bf29ac65cc Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Tue, 20 Apr 2021 14:24:19 +0100 Subject: ptp: Don't print an error if ptp_kvm is not supported Commit 300bb1fe7671 ("ptp: arm/arm64: Enable ptp_kvm for arm/arm64") enable ptp_kvm support for ARM platforms and for any ARM platform that does not support this, the following error message is displayed ... ERR KERN fail to initialize ptp_kvm For platforms that do not support ptp_kvm this error is a bit misleading and so fix this by only printing this message if the error returned by kvm_arch_ptp_init() is not -EOPNOTSUPP. Note that -EOPNOTSUPP is only returned by ARM platforms today if ptp_kvm is not supported.
