No problem at all :)

Yeah, the 3.0 version of the SPDX license list deprecated `GPL-2.0`,
but the kernel still allows `GPL-2.0` and lists it first. I recall
thinking about this before the initial merge, and I think I went with
the original form because the main `COPYING` file still uses that.
After that I am just keeping it consistent, though I am not sure when
the kernel will migrate.

Since you prefer it and it makes sense that someone may want to use it
(`concat` and `expand`) elsewhere, let's go with that. I will add:

    // SPDX-License-Identifier: Apache-2.0 OR MIT

then. Thanks for the very quick reply!
