So you've folded in this fix:
commit 85f024401bf80746ae08b7fd5809a9b16accf0b1
Author: Michael Chan <mchan@xxxxxxxxxxxx>
Date: Tue Jan 29 17:54:44 2013 -0800
serial_core: Fix type definition for PORT_BRCM_TRUMANAGE.
It was mistakenly defined to be 24 instead of the next higher number 25.
which perhaps should be listed in the commit message.
Ben.
