Subject: [PATCH 01/20] dma-mapping: simplify Kconfig dependencies
Date:   Fri, 11 May 2018 09:59:26 +0200
Message-Id: <20180511075945.16548-2-hch@lst.de>
In-Reply-To: <20180511075945.16548-1-hch@lst.de>
References: <20180511075945.16548-1-hch@lst.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

ARCH_DMA_ADDR_T_64BIT is always true for 64-bit architectures now, so we
can skip the clause requiring it.  'n' is the default default, so no need
to explicitly state it.
