Subject: [PATCH] PCI: call dma_debug_add_bus for pci_bus_type in common code
Date:   Mon, 30 Jul 2018 09:38:42 +0200
Message-Id: <20180730073842.16092-1-hch@lst.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

There is nothing arch specific about PCI or dma-debug, so move this
call to common code just after registering the bus type.
