Currently it uses pci_set_power_state() for this purpose, however making a specific assumption about the internal behavior of this function, which has changed recently so that this assumption is no longer satisfied. For this reason, introduce __pci_complete_power_transition() that may be called by the radeonfb driver to complete the power transition of the device. For symmetry, introduce __pci_start_power_transition(). Signed-off-by: Rafael J. Wysocki Acked-by: Jesse Barnes --- Reading git-diff-tree failed
