Here are 2 patches against the 'usb-next' branch of Greg KH's 'usb.git' repo.
The UHCI driver's debugging code uses a lot of sprintf() calls with the large
buffers, leaving some space at the end of the buffers to handle the buffer
overflow.  Using scnprntf() calls instead eliminates the very possibility of
the buffer overflow...

Sergey Shtylyov (2):
  usb: host: uhci-debug: use scnprintf() instead of sprintf()
  usb: host: uhci: remove #define EXTRA_SPACE
