[PATCH] PCI: Add SPDX tag for s390_pci_hpc.c

[PATCH] PCI: Add SPDX tag for s390_pci_hpc.c

[Bjorn Helgaas]

I previously posted patches [1] to add SPDX tags to all drivers/pci files
except drivers/pci/hotplug/s390_pci_hpc.c.  I omitted that one because it
contained only a "License: GPL" comment, which I thought was ambiguous.

However, I think it is actually unambiguous because the file was added with
a 'MODULE_LICENSE("GPL")', and include/linux/module.h shows that means "GPL
v2 or later".

So this patch adds the GPL-2.0+ tag to the file.  I plan to include this
for v4.16 unless somebody objects.

      PCI: Add SPDX GPL-2.0+ to replace implicit GPL v2 or later statement

[PATCH] PCI: Add SPDX GPL-2.0+ to replace implicit GPL v2 or later statement

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

7441b0627e22 ("s390/pci: PCI hotplug support via SCLP") added
s390_pci_hpc.c, which included this license information:

  +MODULE_LICENSE("GPL");

Based on "git show 7441b0627e22:include/linux/module.h", that "GPL" string
means "GPL v2 or later":

   *      "GPL"                           [GNU Public License v2 or later]

0729dcf24832 ("s390: hotplug: make pci_hpc explicitly non-modular")
subsequently replaced the MODULE_LICENSE() with a "License: GPL" comment.

Add SPDX GPL-2.0+ and remove the "License: GPL" comment, relying on the
assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license
identifier to files with no license") that the SPDX identifier may be used
instead of the full boilerplate text.

As I as said in a previous email, context matters a lot in these case
and you made the right choice.
When there is a MODULE_LICENSE and a super terse "GPL" license notice,
the two taken together can provide the proper context e.g. here
GPL-2.0+ rather than a less common GPL-1.0+

Thank you for your efforts there!
