2.6.27-stable review patch.  If anyone has any objections, please let us 
know.

------------------
From: Alan Stern <stern@rowland.harvard.edu>

commit 8fc7aeab3851ed8c3ecf28901ca2c6f0400955c7 upstream

This patch (as1150) fixes a problem in the speedtch driver.  When it
resets the modem during probe it will be unbound from the other
interfaces it has claimed, because it doesn't define a pre_reset and a
post_reset method.

The patch defines "do-nothing" methods.  This fixes Bugzilla #11767.
