Hi all,

Today's linux-next merge of the drm-rust tree got a conflict in:

  scripts/Makefile.build

between commits:

  560a7a9b9267f ("rust: add `const_assert!` macro")
  3a2486cc1da5c ("kbuild: rust: provide an option to inline C helpers into Rust")

from the rust-next tree and commit:

  3cc319d5f433a ("rust: enable the `generic_arg_infer` feature")

from the drm-rust tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Looks good, thanks!
