From 391133fd5adaba319795cd96882d1ea405c41cf6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 13 Feb 2019 08:01:19 +0100 Subject: [PATCH] powerpc/dma: move pci_dma_dev_setup_swiotlb to fsl_pci.c pci_dma_dev_setup_swiotlb is only used by the fsl_pci code, and closely related to it, so fsl_pci.c seems like a better place for it.
