From 7fb0bacd389b9b041164965d31a8c50e8616f7a0 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 19 May 2016 15:52:04 +0900 Subject: tools: moveconfig: skip savedefconfig if .config was not updated If no CONFIG option is moved to the .config, no need to sync the defconfig file. This accelerates the processing by skipping needless "make savedefconfig".
