From 63db51d6583444842093cbc333644031e80f9d8b Mon Sep 17 00:00:00 2001 From: Stewart Smith Date: Wed, 12 Jul 2017 14:29:13 +1000 Subject: [PATCH] xz: add fallthrough annotations to silence GCC7 warning The fallthrough is intentional (or at least appears to be), and I'd rather not have warnings show up in the skiboot build at all.
