From 860dd4424f344400b491b212ee4acb3a358ba9d9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 21 Nov 2017 14:23:37 +0100 Subject: scsi: dma-mapping: always provide dma_get_cache_alignment Provide the dummy version of dma_get_cache_alignment that always returns 1 even if CONFIG_HAS_DMA is not set, so that drivers and subsystems can use it without ifdefs.
