From eb7a900f63752517ba6e6378215cdc34bcd1c0dc Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Fri, 21 Oct 2011 15:45:09 +0200 Subject: [PATCH] libpayload: fix bulk transfers on OHCI controllers Time for the brown paper bag: OHCI controllers are not happy when told to send data, but with obviously wrong addresses. It helps to write the addresses into the data structures.
