From 3fa4680b860bf48b437d6a2c039789c4abe202ae Mon Sep 17 00:00:00 2001 From: Shilpasri G Bhat Date: Fri, 12 Jan 2018 12:43:53 +0530 Subject: [PATCH] cpufreq: powernv: Dont assume distinct pstate values for nominal and pmin Some OpenPOWER boxes can have same pstate values for nominal and pmin pstates. In these boxes the current code will not initialize 'powernv_pstate_info.min' variable and result in erroneous CPU frequency reporting. This patch fixes this problem.
