Hehe, thanks I'll fix in the next spin.

Let me try clarifying this further, how about:
copyleft-next-0.3.1 is explicitly compatible with GPLv2 (or later) and can therefore be used for kernel code. Despite this, if you use copyleft-next-0.3.1 on Linux, the recommended practice is to express dual licensing with GPL using in the SPDX license identifiers by using by the OR operator.

OK thanks for the recommendation, I'll leave it at:
+ SPDX-License-Identifier: GPL-2.0 OR copyleft-next-0.3.1 + SPDX-License-Identifier: GPL-2.0-or-later OR copyleft-next-0.3.1
