From a8651194f9f61406cb8926feeeb7829258295b2a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 30 Jul 2018 09:38:42 +0200 Subject: [PATCH] PCI: Call dma_debug_add_bus() for pci_bus_type from PCI core There is nothing arch-specific about PCI or dma-debug, so call dma_debug_add_bus() from the PCI core just after registering the bus type. Most of dma-debug is already generic; this just adds reporting of pending dma-allocations on driver unload for arches other than powerpc, sh, and x86.
