...or just apply it from this mail. This fixes a regression since -rc1:
Some machines, esp. PPC_PMAC, cannot suspend if ohci1394 is loaded.

Subject: ieee1394: ohci1394: revert fail on error in suspend

Some errors during preparation for suspended state can be skipped with a
warning instead of a failure of the whole suspend transition, notably an
error in pci_set_power_state.
