From 0749739009c894564d14ddf50ccc39ae723ad30c Mon Sep 17 00:00:00 2001 From: kib Date: Sun, 14 Apr 2013 14:02:34 +0000 Subject: Usnure that PCI bus BIS_GET_DMA_TAG() method sees the actual PCI device which makes the request for dma tag, instead of some descendant of the PCI device, by creating a pass-through trampoline for vga_pci and ata_pci buses.
