This avoids the deadlock while also ensuring proper\nconfig space access serialization during the reset.\n\nThe pci_dev_get/put calls are also removed as they were unnecessary -\nthe driver-owned workqueue is destroyed in pdsc_remove(), guaranteeing\nthe work completes before remove returns. The PCI core holds its\nreference to pci_dev throughout the entire unbind sequence."
