pm_runtime_allow() is not needed for ACP child platform devices. Replace pm_runtime_allow() with pm_runtime_mark_last_busy() & pm_runtime_set_active() in pm_runtime enable sequence for ACP child platform drivers.
Can you explain what prompted this?
Does this fix a particular bug, or is it just to correct things? If it fixes a particular bug; I think it should be split up across 5 patches (one for each APU) and then appropriate Fixes tags applied for each on the code they're fixing.
