Subject: [PATCH 3/3] ARM: errata 430973: move !ARCH_MULTIPLATFORM to Kconfig
Date: Thu, 23 Jul 2015 02:48:03 +0200	[thread overview]
Message-ID: <1437612483-30160-4-git-send-email-sre@kernel.org> (raw)
In-Reply-To: <1437612483-30160-1-git-send-email-sre@kernel.org>

Having the !ARCH_MULTIPLATFORM dependency in the Kconfig file results
in one option less to think about when configuring the kernel.
