Uf, I don't know what version that was.. I think I have

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 12
EXTRAVERSION =-rc1-mm1

and that says:

#define PMSG_FREEZE ((__force pm_message_t) 3)

... I certainly have _FREEZE defined as 1 in my local tree, but I do
not see that change in -mm yet.

Possibly pm.h changes went in faster than pci.c or something like
that?

I reproduced it here.. I do not know who introduced
platform_pci_choose_state, but it is *very* wrong. It returns
it. Should it return pci_power_t? It probably should to match
pci_choose_state, but that int is retyped to pm_message_t. Oops.
