PCI / PCIe portdrv: Fix pcie_portdrv_slot_reset()
After commit c82f63e411f1b58427c103bd95af2863b1c96dd1 (PCI: check saved state before restore) pcie_portdrv_slot_reset() may not work correctly if dev->error_state is equal to pci_channel_io_frozen, because dev->state_saved need not be set at that time. Fix this issue by setting dev->state_saved before pci_restore_state() is called in pcie_portdrv_slot_reset(). Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
