2018-01-26	PCI: Add SPDX GPL-2.0 when no license was specified	Bjorn Helgaas	1	-0/+1
	b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") added SPDX GPL-2.0 to several PCI files that previously contained no license information. Add SPDX GPL-2.0 to all other PCI files that did not contain any license information and hence were under the default GPL version 2 license of the kernel.
