From 7acffde7a949cd8bb08fd550faae519140c8a609 Mon Sep 17 00:00:00 2001 From: Rex Zhu Date: Wed, 25 Jul 2018 11:51:46 +0800 Subject: [PATCH] drm/amdgpu: fix a reversed condition commit ccf9ef0b0d10434dec5046bcfc4e834a7b1830fd upstream. This test was reversed so it would end up leading to vddnb value can't be read via hwmon on APU.
