In 08810a4119aaebf6318f209ec5dd9828e969cba4 setting dev->power.direct_complete was made conditional on pm_runtime_suspended().
The justification was: While at it, make the core check pm_runtime_suspended() when setting power.direct_complete so that it doesn't need to be checked by ->prepare callbacks.
However, this breaks resuming from suspend on those newer HP laptops if the amdgpu driver is used (due to hybrid intel+radeon graphics). Given the justification for the change, undoing it seems best as it appears to have unintended side effects.
