Bug description:
  [Impact]
  A bug in the implementation of the -evtouch driver's input configuration can lead to crashes due to failing to detect the end-of-list marker for the configuration options list.

  [Development Solution]
  Patch incorporated into -evtouch in natty.

  [Stable Solution]
  We carry the same upstream version of -evtouch in lucid, maverick, and natty, so the same patch can be used in all three versions without modification.

  [Test Case]
  See original report

  [Regression Potential]
  I think basically none.  This is clearly incorrect code.

  The scope of a regression would be quite constrained as well, since
  -evtouch is used only for a focused class of hardware.

  [Original Report]
  HW configuration: MX51 EVK board
  SW configuration:
  1. Install xserver-xorg-input-evtouch page (version: 0.8.8-0ubuntu6.1)
  2. Add fdi file by "vi /usr/share/hal/fdi/policy/20thirdparty/50-mxc-ts.fdi":
  <?xml version="1.0" encoding="ISO-8859-1"?>
  <deviceinfo version="0.2">
    <device>
      <match key="info.product" contains="mxc_ts">
          <merge key="input.x11_driver" type="string">evtouch</merge>
      </match>
    </device>
  </deviceinfo>
  3. reboot the board, X crash. The backtrace is as follows:
  Program received signal SIGSEGV, Segmentation fault.
  0x402edae4 in strlen () from /lib/libc.so.6
  (gdb) backtrace
  #0  0x402edae4 in strlen () from /lib/libc.so.6
  #1  0x00096a4c in xf86optionListCreate ()
  #2  0x0008f8d8 in xf86CollectInputOptions ()
  #3  0x42d46b0c in EVTouchPreInit (drv=<value optimized out>, dev=0x329b88,
      flags=<value optimized out>) at evtouch.c:1167
  #4  0x000861c8 in ?? ()
  #5  0x000861c8 in ?? ()

  However if i down-grade xserver-xorg-input-evtouch to version
  0.8.8-0ubuntu3, Touch screen works fine.

  So what's the possible difference cause this issue?
