The diff was made from the wrong directory; the pathname should start with the name of the directory containing the top-level source files. And your patch file should include a "---" line after the Signed-off-by line. The diff compares the wrong files. That is, it compares a .c file to something that isn't a .c file. This means that when someone applies your patch, they won't be able to compile the new code. Finally, I don't understand how this patch could make any difference. At the time the ->attach() routine runs, the device should already be locked. A better strategy might be to call usb_queue_device_reset().
