Old "GPL" text as GPL v2 or "later", and the "later" keyword is the problem. This patch is to fix it. How about the SPDX license string? The same definition? > -- > Dmitry

The same definition? No, MODULE_LICENSE() is sorely for symbol resolution during module loading, so GPL vs GPLv2 or later, etc is all the same. SPDX denotes the actual license for the source code that governs derivative works, etc. and I did not change it - it is left exactly as you sent it: // SPDX-License-Identifier: GPL-2.0-only Thanks.
