From: Palmer Dabbelt <palmerdabbelt@xxxxxxxxxx> I recently build the RISC-V port with LLVM trunk, which has introduced a new warning when casting from a pointer to an enum of a smaller size. This patch simply casts to a long in the middle to stop the warning. I'd be surprised this is the only one in the kernel, but it's the only one I saw.
