Hi Leon,

Just:

+MODULE_LICENSE("GPL v2");

to

quoted

+builtin_platform_driver(mc_pcie_driver);
+MODULE_LICENSE("GPL");

or does

need to change as well, to:
+// SPDX-License-Identifier: GPL

You should change only MODULE_LICENSE(..) and leave SPDX as is.
See Documentation/process/license-rules.rst

  448     "GPL v2"                      Same as "GPL". It exists for historic

Thanks
