From: Christoph Hellwig Date: Tue, 21 Nov 2017 13:23:37 +0000 (+0100) Subject: scsi: dma-mapping: always provide dma_get_cache_alignment X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc2b3046048bc193def020ef9d871f4edb3f47ba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git scsi: dma-mapping: always provide dma_get_cache_alignment commit 860dd4424f344400b491b212ee4acb3a358ba9d9 upstream. 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.
