I tried to reproduce the last warning (intelfbhw_validate_mode), but I failed to produce it.
I think my reproducer is correct, but it does not make any warning.
Can you tell me which part was wrong?

  clang -O2 -flto=thin -fsanitize=integer-divide-by-zero -c -o intelfb.o intelfb.i
  ld.lld -m elf_x86_64 -r -o intelfb.lto.o --whole-archive intelfb.o
  objtool orc generate --module --no-fp --no-unreachable --uaccess --mcount intelfb.lto.o

I use these commands, and I attached the `intelfb.i` file.F21595840: intelfb.i <https://reviews.llvm.org/F21595840>
