From efa17194581bdfca0986dabc178908bd7c21ba00 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Tue, 22 Jan 2013 22:33:46 +0100 Subject: [PATCH] cpufreq: Add module aliases for acpi-cpufreq The acpi core will call request_module("acpi-cpufreq") on subsystem init, but this will fail if the module isn't available at that stage of boot. Add some module aliases to ensure that udev can load the module on Intel and AMD systems with the appropriate feature bits - I /think/ that this will also work on VIA systems, but haven't verified that.
