Subject: [PATCH 1/6] dma-mapping: simplify Kconfig dependencies
Date: Fri, 18 May 2018 15:45:40 +0200 [thread overview]
Message-ID: <20180518134545.5036-2-hch@lst.de> (raw)
In-Reply-To: <20180518134545.5036-1-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.
