Miller" Subject: [PATCH V2 21/35] cpufreq: p4: Covert to light weight ->target_index() routine Date: Tue, 13 Aug 2013 19:02:34 +0530 Message-Id: X-Mailer: git-send-email 1.7.12.rc2.18.g61b472e In-Reply-To: References: In-Reply-To: References: Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2402 Lines: 68 This patch converts existing .target() to newly defined light weight .target_index() routine for this driver. CPUFreq core will call cpufreq_frequency_table_target() before calling this routine and will pass index to it. Cc: David S.
