From 5a90c24ad0283434f60ed2e1a628c9e6134d1fdc Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 4 May 2022 09:23:28 -0400 Subject: [PATCH] Revert "drm/amdgpu: disable runpm if we are the primary adapter" This reverts commit b95dc06af3e683d6b7ddbbae178b2b2a21ee8b2b. This workaround is no longer necessary. We have a better workaround in commit f95af4a9236695 ("drm/amdgpu: don't runtime suspend if there are displays attached (v3)").
