From 237ede16ba5bcd4d6c612ea280518c48ca31986c Mon Sep 17 00:00:00 2001 From: "Srivatsa S. Bhat" Date: Tue, 29 Apr 2014 00:24:27 +0530 Subject: [PATCH] cpufreq: powernow-k6: Fix incorrect comparison with max_multipler The value of 'max_multiplier' is meant to be used for comparison with clock_ratio[index].driver_data, not the index itself! Fix the code in powernow_k6_cpu_exit() that has this bug. Also, while at it, make the for-loop condition look for CPUFREQ_TABLE_END, instead of hard-coding the loop count to 8.
