Subject[PATCH v4 1/6] tools/bootconfig: Fix a build error accroding to undefined fallthrough
Date
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.

Cc: stable@vger.kernel.org
Fixes: 4c1ca831adb1 ("Revert "lib: Revert use of fallthrough pseudo-keyword in lib/"")
Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org>
