From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jonghwan Choi Subject: [PATCH 2/2] cpufreq: Remove exynos_sort_descend_freq_table in exynos5440-cpufreq.c Date: Tue, 29 Apr 2014 14:24:05 +0900 Message-ID: <000701cf636b$3d1d13c0$b7573b40$@samsung.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Return-path: Received: from mailout3.samsung.com ([203.254.224.33]:25388 "EHLO mailout3.samsung.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751975AbaD2FYH (ORCPT ); Tue, 29 Apr 2014 01:24:07 -0400 Content-language: ko Sender: linux-samsung-soc-owner@vger.kernel.org List-Id: linux-samsung-soc@vger.kernel.org To: "'open list:CPU FREQUENCY DRI...'" , linux-arm-kernel@lists.infradead.org, linux-samsung-soc@vger.kernel.org Cc: "'Rafael J. Wysocki'" , 'Viresh Kumar' , 'Kukjin Kim' After applying "PM / OPP: Use list_for_each_entry_reverse instead of list_for_each_entry", cpufreq table is sorted int descending order. So exynos_sort_descend_freq_table doesn't need anymore.
