ACPI / processor: Get power info before updating the C-states
commit f427e5f1cf75bba84cccdac1d8a90552d9ae1065 upstream. acpi_processor_get_power_info() has to be called before acpi_processor_setup_cpuidle_states() to have the latest information available. This fixes the missing C-state information after AC-->DC transition. Signed-off-by: Thomas Schlichter <thomas.schlichter@web.de> Signed-off-by: Rafael J.
