From f427e5f1cf75bba84cccdac1d8a90552d9ae1065 Mon Sep 17 00:00:00 2001 From: Thomas Schlichter Date: Sat, 19 Jan 2013 00:28:22 +0100 Subject: [PATCH] ACPI / processor: Get power info before updating the C-states 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 Cc: Signed-off-by: Rafael J.
