The v2 incorporates Lukas's suggestion to use PCI_POSSIBLE_ERROR() and carries Mathias's Acked-by. I couldn't find it in mainline or the xHCI/USB integration branches. Are there any remaining concerns, or could this be queued? Should it go through Mathias's xHCI tree or directly through Greg's USB tree? Thanks, Haowen
