USB: avoid using urb->pipe in usbcore
This patch (as946) eliminates many of the uses of urb->pipe in usbcore. Unfortunately there will have to be a significant API change, affecting all USB drivers, before we can remove it entirely. This patch contents itself with changing only the interface to usb_buffer_map_sg() and friends: The pipe argument is replaced with a direction flag. That can be done easily because those routines get used in only one place. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
