Subject: [PATCH 1/5] cpufreq: Unify sysfs attribute definition macros
Date: Mon, 22 Mar 2010 19:38:37 +0100 [thread overview]
Message-ID: <1269283121-11894-2-git-send-email-bp@amd64.org> (raw)
In-Reply-To: <1269283121-11894-1-git-send-email-bp@amd64.org>
From: Borislav Petkov <borislav.petkov@amd.com>
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.
