[PATCH -next] powernv: cpufreq: Fix uninitialized lpstate_idx in gpstates_timer_handler
From: Akshay Adiga <hidden>
Date: 2016-11-14 12:00:36
lpstate_idx remains uninitialized in the case when elapsed_time
is greater than MAX_RAMP_DOWN_TIME. At the end of rampdown
global pstate should be equal to local pstate.
Fixes: 20b15b766354 ("cpufreq: powernv: Use PMCR to verify global and
localpstate")
