========================================
if it is merely wrong annotation problem (I think so), fixing patch is here.
=====
Subject: [PATCH] mpt: timer annotaion fix in mpt_config()
The mpt_config() call to init_timer(), not init_tiemr_on_stack().
but all caller of the mpt_config() create a timer object on stack.
Then, if CONFIG_DEBUG_OBJECTS=y, kernel output following warning at boot time.
ODEBUG: object is on stack, but not annotated
