PCI: Add SPDX GPL-2.0 when no license was specified2018-01-26T17:45:16+00:00Bjorn Helgaasbhelgaas@google.com2018-01-26T17:45:16+00:00urn:sha1:7328c8f48d1895b3fec98b0b319cfb856b4c4fa1
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.
