Subject: [PATCH] tools/bootconfig: Fix a build error accroding to undefined fallthrough
Date: Thu, 13 May 2021 12:06:33 +0900	[thread overview]
Message-ID: <162087519356.442660.11385099982318160180.stgit@devnote2> (raw)

Since the "fallthrough" is defined only in the kernel, building
lib/bootconfig.c as a part of user-space tools causes a build

Add a dummy fallthrough to avoid the build error.

Fixes: 4c1ca831adb1 ("Revert "lib: Revert use of fallthrough pseudo-keyword in lib/"")
