From 0a91e551527a7b931d36f4822b97e70536bd2bb3 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 25 Apr 2016 13:03:15 +0100 Subject: [PATCH] tools/power turbostat: fix error case overflow read of slm_freq_table[] When i >= SLM_BCLK_FREQS, the frequency read from the slm_freq_table is off the end of the array because msr is set to 3 rather than the actual array index i. Set i to 3 rather than msr to fix this.
