From 4bd8dd0d61f961e6c13cc118d4ebbdba57f8561f Mon Sep 17 00:00:00 2001 From: Yongzhi Liu Date: Tue, 18 Jan 2022 15:11:51 -0500 Subject: drm/amdgpu: Add missing pm_runtime_put_autosuspend pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code, thus a matching decrement is needed on the error handling path to keep the counter balanced.
