In this case, the problem is that (@ (guix build-system linux-module)
lower) assumes that ‘linux’ is a <package>:

    (build-inputs `(,@(if source
                          `(("source" ,source))
                          '())
                    ,@native-inputs
                    ;; TODO: Remove "gmp", "mpfr", "mpc" since they are
                    ;; only needed to compile the gcc plugins.  Maybe
                    ;; remove "flex", "bison", "elfutils", "perl",
                    ;; "openssl".  That leaves very little ("bc", "gcc",
                    ;; "kmod").
                    ,@(package-native-inputs linux)   ;<----- HERE

I suppose you could add a special-case for (inferior-package? linux).
Not pretty, but it’d do the job.

If we want to go further, we’ll have to end up with GOOPS…

HTH!
