Subject: [PATCH 026/114] arch: Kconfig: pedantic formatting
Date: Mon, 11 Mar 2019 14:17:38 +0100 [thread overview]
Message-ID: <1552310346-7629-27-git-send-email-info@metux.net> (raw)
In-Reply-To: <1552310346-7629-1-git-send-email-info@metux.net>
Formatting of Kconfig files doesn't look so pretty, so let the
Great White Handkerchief come around and clean it up.
