Subject: [PATCH 3/3] kbuild: add -Werror=implicit-int flag unconditionally
Date: Fri, 14 Dec 2018 17:05:39 +0900	[thread overview]
Message-ID: <1544774739-13471-3-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1544774739-13471-1-git-send-email-yamada.masahiro@socionext.com>

This flag is documented in the GCC 4.6 manual, and recognized by
Clang as well. Let's rip off the cc-option switch.
