From d5554e5096a1bf27490adbddcc329fb77556ef9b Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Wed, 2 Jun 2021 17:18:50 +0900 Subject: [PATCH] FROMLIST: tools/bootconfig: Fix a build error accroding to undefined fallthrough Since the "fallthrough" is defined only in the kernel, building lib/bootconfig.c as a part of user-space tools causes a build error. Add a dummy fallthrough to avoid the build error. Picking this up FROMLIST to get the fix ASAP. It is likely to be accepted upstream.
