Subject: [PATCH] iommu/dma: Fix NEED_SG_DMA_LENGTH dependency
Date: Mon, 29 Feb 2016 11:13:39 +0000	[thread overview]
Message-ID: <189f8d7a6b1598108dc8e9f1777c67b07a4bd781.1456744313.git.robin.murphy@arm.com> (raw)

IOMMU_DMA does indeed depend on scatterlists having a DMA length, but
the NEED_SG_DMA_LENGTH symbol should be selected, not depended upon.

Reported-by: Arnd Bergmann <arnd@arndb.de>
