Subject: [ 21/22] ACPI / processor: Get power info before updating the C-states
Date: Thu, 24 Jan 2013 13:15:42 -0800 [thread overview]
Message-ID: <20130124211511.549567120@linuxfoundation.org> (raw)
In-Reply-To: <20130124211504.701368763@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Schlichter <thomas.schlichter@web.de>
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.
