Subject: [dpdk-dev] [PATCH 1/2] bus/pci: fix driver detach clear
Date: Tue, 12 Nov 2019 08:47:38 +0000
Message-ID: <1573548459-6931-1-git-send-email-matan@mellanox.com> (raw)

When a rte_device is unplugged, the driver should be detached from the
device.

The PCI detach driver operation wrongly didn't clear the driver from the
device structure what remain the device in probe state from the EAL
point of view.

Clear the driver in driver detach successful operation.

Fixes: dbe6b4b61b0e ("pci: probe or close device")
