I checked out your branch and get a compiler error about missing pwm.c:

$ make W=1 LLVM=1 ARCH=riscv
  CALL    scripts/checksyscalls.sh
  BINDGEN rust/bindings/bindings_helpers_generated.rs
rust/helpers/helpers.c:34:10: fatal error: 'pwm.c' file not found
Unable to generate bindings: clang diagnosed error: rust/helpers/helpers.c:34:10: fatal error: 'pwm.c' file not found

make[2]: *** [rust/Makefile:371: rust/bindings/bindings_helpers_generated.rs] Error 1
make[2]: *** Deleting file 'rust/bindings/bindings_helpers_generated.rs'
make[1]: *** [/home/pdp7/linux/Makefile:1280: prepare] Error 2
make: *** [Makefile:248: __sub-make] Error 2

Did I do something wrong?
