Well it's the debugobjects stuff complaining about
init_timer(&pCfg->timer) in mpt_config().

I spent a minute trying to work out what the heck
debug_object_is_on_stack() is trying to tell me, but it seems that code
was designed to only be used by Thomas, so let's cc him and ask.

Thomas, could we have some nice code comments please, so that random
kernel developers don't need to go and reverse engineer the
debugobjects design before they can work out what they did wrong?

Noticing that every caller of mpt_config has its CONFIGPARMS struct
declared on the stack and thus the &pCfg->timer is always on the stack
I changed init_timer() to init_timer_on_stack() and it seems to have
shut up.....

Admittedly I don't know either the debugobject code or the mpt code,
but when the timer is on the stack and we have an "init when the timer
is on the stack" it seemed like an easy enough fix.

yeah, I don't have a clue why that warning came out either, and I don't
know what it's trying to tell us.  This is a bad situation!

Thomas, please help?
