From 46053c73685411915d3de50c5a0045beef32806b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 24 Aug 2018 10:29:02 +0200 Subject: dma-mapping: clear dev->dma_ops in arch_teardown_dma_ops There is no reason to leave the per-device dma_ops around when deconfiguring a device, so move this code from arm64 into the common code.
