From da27f69d6a4eaf7bdaaad9d9e1b997a1c8f186aa Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 25 Apr 2017 15:57:21 +0530 Subject: thermal: cpu_cooling: get_level() can't fail The frequency passed to get_level() is returned by cpu_power_to_freq() and it is guaranteed that get_level() can't fail. Get rid of error code.
