Subject: [PATCH] misc: pci_endpoint_test: Ensure relationship between miscdev and PCI
Date:   Tue,  6 Jul 2021 17:43:10 +0200

Set the parent pointer of the misc device to ensure a relationship
between PCI and misc dev. That way it is possible to see in
/sys/class/misc/ which pci_endpoint_test instance serves what
PCI device.
