From aab18da44f243cf59b4dee335ea50b32f529b5b0 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 31 Oct 2014 17:45:22 +1100 Subject: [PATCH] hwmon: (ibmpowernv) Quieten when probing finds no device Because we build kernels with drivers built in for many platforms, it's normal for the ibmpowernv driver to be loaded on systems that don't have the appropriate hardware. Currently the driver spams the log with: ibmpowernv ibmpowernv.0: Opal node 'sensors' not found ibmpowernv: Platfrom driver probe failed But there is no error, this machine is not a powernv and doesn't have the hardware. So change the sensors message to dev_dbg(), and only print an error about the probe failing if it's not ENODEV. Also fix the spelling of "Platfrom" and print the actual error value.
