Subject: [PATCH] kconfig: suppress "configuration written to .config" for syncconfig
Date: Thu, 16 Aug 2018 16:48:26 +0900	[thread overview]
Message-ID: <1534405706-18467-1-git-send-email-yamada.masahiro@socionext.com> (raw)

The top-level Makefile invokes "make syncconfig" when necessary.
Then, Kconfig displays the following message when .config is updated.

  #
  # configuration written to .config
  #

It is distracting because "make syncconfig" happens during the build
stage, and does nothing important in most cases.
