Wysocki The cpu_defaults structure is redundant, because it only contains one member of type struct pstate_funcs which can be used directly instead of struct cpu_defaults. For this reason, drop struct cpu_defaults, use struct pstate_funcs directly instead of it where applicable and rename all of the variables of that type accordingly. Signed-off-by: Rafael J.
