From 15854edd193ae5d9daf8f50ce5f9f1724cebe344 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Apr 2019 10:02:20 +0200 Subject: x86/pci: Clean up usage of X86_DEV_DMA_OPS We have supported per-device dma_map_ops in generic code for a long time, and this symbol just guards the inclusion of the dma_map_ops registry used for vmd. Stop enabling it for anything but vmd. No change in functionality intended.
