 How to port a serial driver to driver model
 ===========================================
 
 Almost all of the serial drivers have been converted as at January 2016. These

-   serial_bfin.c
-   serial_pxa.c
+   * serial_bfin.c
+   * serial_pxa.c
 
 The deadline for this work was the end of January 2016. If no one steps
