From 6761c4bfee681c306bbe6599951e74826660be47 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Tue, 21 Feb 2023 15:21:19 +0800 Subject: [PATCH] drm/amd/pm: no pptable resetup on runpm exiting It is assumed the pptable used before runpm is same as the one used afterwards. Thus, we can reuse the stored copy and do not need to resetup the pptable again.
