From d14feb5ee4a46218f92b21ed52338b64130a151b Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Fri, 23 Jun 2006 21:36:07 +0100 Subject: [PATCH] [PATCH] USB: au1200: EHCI and OHCI fixes I received an DBAU1200 eval kit from AMD a few days ago and tried to enable the USB2 port, but the current linux-2.6 GIT did not even compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and CONFIG_USB_OHCI set. Furthermore, in ehci-hcd.c, platform_driver_register() was called with an improper argument of type 'struct device_driver *' which of course ended up in a kernel oops. How could that ever have worked on your machines? Anyway, here's a trivial patch that makes the USB subsystem working on my board for both OHCI and EHCI. It also removes the /* FIXME use "struct platform_driver" */.
