From 2fde9ab218b7f8446c2428b7f9dad602afce8be6 Mon Sep 17 00:00:00 2001 From: Rex Zhu Date: Fri, 5 May 2017 16:50:36 +0800 Subject: [PATCH] drm/amd/powerplay: refine pwm1_enable callback functions for vi. Use the new enums for setting and getting the fan control mode. Fixes problems due to previous inconsistencies between enums.
