Revision bd91b56cb3b27492963caeb5fccefe20a986ca8d authored by Thomas Tai on 26 July 2018, 17:13:04 UTC, committed by Bjorn Helgaas on 26 July 2018, 17:13:04 UTC
When an fatal error is received by a non-bridge device, the device is
removed, and pci_stop_and_remove_bus_device() deallocates the device
structure. The freed device structure is used by subsequent code to send
uevents and print messages.
Hold a reference on the device until we're finished using it. This is not
an ideal fix because pcie_do_fatal_recovery() should not use the device at
all after removing it, but that's too big a project for right now.
Fixes: 7e9084b36740 ("PCI/AER: Handle ERR_FATAL with removal and re-enumeration of devices")
