From 4708f31885a0d3e41a03c39501df697e73406f6a Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Mon, 6 Apr 2020 20:08:00 -0700 Subject: mm: prevent a warning when casting void* -> enum 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.
