What is supposed to be checked here,
and how should that be fixed outside
the trivial case where all upstream
files are under the same licence?

As an example, think of a kernel patch that touches two files:
1. source file with SPDX-License-Identifier: GPL-2.0
2. userspace header with SPDX-License-Identifier: GPL-2.0 WITH 
Linux-syscall-note

"same license as upstream" are two different licences for different 
parts of the patch, and the Debian kernel maintainer is usually not
the author of a patch cherry-picked from upstream.

Want copyright information do you want to make mandatory for patches
in src:linux?

DEP-5 listing of every patch, and for patches like the example above a 
detailed explanation which parts of a patch are under which licence?

IMHO it would be more reasonable to treat debian/patches/
as special case, defaulting to "same licence as the patched code".
