From 89ee9f7680031d7df91a1a27abac69e034c2e892 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 29 Mar 2017 22:48:59 -0500 Subject: PCI: Add device disconnected state Add a new state to pci_dev to be set when it is unexpectedly disconnected. The PCI driver tear down functions can observe this new device state so they may skip operations that will fail. The pciehp and pcie-dpc drivers are aware when the link is down, so these set the flag when their handlers detect the device is disconnected.
