After a source tree build of the kernel, and having used the `RSCPP`
rule, running `rustfmt` fails with:
error: macros that expand to items must be delimited with braces or followed by a semicolon
--> rust/kernel/arch_static_branch_asm.rs:1:27

1 | ...ls!("1: jmp " ... ".popsection \n\t")
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

help: change the delimiters to curly braces

1 | ::kernel::concat_literals!{"1: jmp " ... ".popsection \n\t"}

help: add a semicolon
