Subject: [dpdk-dev] [PATCH] eal/hotplug: suppress one error log on primary process
Date: Wed, 19 May 2021 14:45:48 +0800
Message-ID: <1621406749-15536-1-git-send-email-changpeng.liu@intel.com> (raw)

This is a normal case that the primary process already
owned one PCI device while the secondary process try to
attach it, so suppress the error log here to exclude
this case.
