[Linux-parport] [PATCH] fix parport_serial_pci_resume() ignoring return value from pci_enable_device()

[Jiri Kosina]

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?)
