v2->v3: add a wrap function pci_dsn_init, fix other typo error and git am error.
		Thanks for Don Dutile and Paul Bolle 's review,comments and test.
v1->v2: Modify pci_get_dsn to pci_device_serial_number,
	    power off slot before remove the old device during resume to avoid
		old .remove() method to touch new hardware.
		Fix other typo and fail check problems.
		Split the list_empty() guard into new patch.
		Thanks for Bjorn's review and comments.
