to delete that mention in the TODO file.

 TPCI-200
 --------
 
-* It receives the name of the mezzanine plugged in each slot by SYSFS.
-  No autodetection supported yet, because the mezzanine driver could not be
-  loaded at the time that the tpci200 driver loads.
-
 * It has a linked list with the tpci200 devices it is managing. Get rid of it
   and use driver_for_each_device() instead.
