All headers from 'include/dt-bindings/' must be verified by checkpatch
together with Documentation bindings, because all of them are part of
the whole DT bindings system.
The requirement is dual licensed and matching string:
'GPL-2.0-only OR BSD-2-Clause'
The issue was found during patch review:

I prefer aligning to open parens

And if it's really a strict bit about the required license,
why not make it match exactly?
$spdx_license !~ /GPL-2\.0(?:-only|-or-later|\+)? OR BSD-2-Clause/) {

I think, it's a good idea.

I've noticed it too, asked Krzysztof about this situation in the below
review:
https://lore.kernel.org/all/9d176288-cd7c-7107-e180-761e372a2b6e@linaro.org/
Krzysztof mentioned, that he checked the purpose to have different
license each time manually. But by default, it should be strict.
