Revision 6e0eda3c389887168455b92b6f7b48f552227067 authored by Konstantin Khlebnikov on 14 March 2013, 14:49:37 UTC, committed by Bjorn Helgaas on 03 April 2013, 00:03:09 UTC
This is a fix for commit 7897e60227 ("PCI: Disable Bus Master
unconditionally in pci_device_shutdown()").  Vivek reported that
with this commit, kexec failed because none of his SATA disks
came up.

A ->shutdown() callback might put the device in D3cold, which means config
space is no longer available.
