From 8b373ffc797713337f42f0e58d832d5cae86752c Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Mon, 13 Mar 2017 10:18:45 +0800 Subject: usb: ehci: use bus->sysdev for DMA configuration Set the dma for ehci from sysdev. The sysdev is pointing to device that is known to the system firmware or hardware.
