From 8d9b409b1a42db9986dfe2d510fe7aea7a98a203 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 24 Apr 2018 08:58:47 +0200 Subject: mips,unicore32: swiotlb doesn't need sg->dma_length Only mips and unicore32 select CONFIG_NEED_SG_DMA_LENGTH when building swiotlb. swiotlb itself never merges segements and doesn't accesses the dma_length field directly, so drop the dependency.
