Subject: [PATCH] fix parport_serial_pci_resume() ignoring return value from
pci_enable_device()
Fix parport_serial_pci_resume() ignoring return value from
pci_enable_device().
(I guess that the parport_serial_pci_remove() is the right way(tm) to
remove the device from the system in non-destructive way even in case
pci_enable_device() failed. Tim?)
