Subject: [PATCH 01/20] dma-mapping: simplify Kconfig dependencies
Date: Fri, 11 May 2018 09:59:26 +0200	[thread overview]
Message-ID: <20180511075945.16548-2-hch@lst.de> (raw)
Message-ID: <20180511075926.OfZpKwTfwyKNwbRqDyjpntUNZOvyaudzwz20Yn06KKI@z> (raw)
In-Reply-To: <20180511075945.16548-1-hch@lst.de>

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.
