Subject: [PATCH 3.12 007/181] intel_idle: close avn_cstates array with correct marker

From: Jiang Liu <jiang.liu@...ux.intel.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 88390996c95b879ba365888199b45ace3f5ca80b upstream.

Close avn_cstates array with correct marker to avoid overflow
in function intel_idle_cpu_init().

[rjw: The problem was introduced when commit 22e580d07f65 was merged
 on top of eba682a5aeb6 (intel_idle: shrink states tables).]

Fixes: 22e580d07f65 (intel_idle: Fixed C6 state on Avoton/Rangeley processors)
