As HD-audio driver does deferred probe internally via workqueue, the driver might go into the mixed state doing both probe and remove when the module gets unloaded during the probe work. This eventually triggers an Oops, unsurprisingly. For avoiding this race, we just need to flush the pending probe work explicitly before actually starting the resource release.
