From 6dad2a29646ce3792c40cfc52d77e9b65a7bb143 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Wed, 31 Mar 2010 21:56:46 +0200 Subject: cpufreq: Unify sysfs attribute definition macros Multiple modules used to define those which are with identical functionality and were needlessly replicated among the different cpufreq drivers. Push them into the header and remove duplication. Signed-off-by: Borislav Petkov LKML-Reference: <1270065406-1814-7-git-send-email-bp@amd64.org> Reviewed-by: Thomas Renninger Signed-off-by: H.
