I can run a scancode scan to list modules with a license that does not match their MODULE_LICENSE (irrespective of whether they have an SPDX id already or not) I can then either provide a CSV (or provide an eventually big patch). Which do you prefer? What should be the tree to run this on: Yours? usb? Linus's? tip of the tree or a tag? If you prefer a patch, what should be the rationale when licenses do not match? I guess update the MODULE_LICENSE to match the license comment? -- Cordially Philippe Ombredanne
