Subject: tools/bootconfig: Fix a build error accroding to undefined fallthrough
From: Masami Hiramatsu <mhiramat@xxxxxxxxxx>
commit 824afd55e95c3cb12c55d297a0ae408be1779cc8 upstream.
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.
