Subject: [PATCH 5/6] scs: Remove references to asm/scs.h from core code
Date: Fri, 15 May 2020 18:27:55 +0100	[thread overview]
Message-ID: <20200515172756.27185-6-will@kernel.org> (raw)
In-Reply-To: <20200515172756.27185-1-will@kernel.org>

asm/scs.h is no longer needed by the core code, so remove a redundant
header inclusion and update the stale Kconfig text.
