From 3044dd05289d6c768c7c5d00f58208fc1f3927f3 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada <masahiroy@kernel.org> Date: Fri, 1 May 2020 15:01:41 +0900 Subject: [PATCH] kbuild: invoke syncconfig if autoconf.h is missing If include/generated/autoconf.h is accidentally lost somehow, there is no clear way to fix it. Make it self-healing.
