While testing fixes for SoundWire race conditions initially reported in [1], I found additional issues in codec drivers. When the order in which drivers are probed is changed, multiple errors are reported, from unbalanced pm_runtime_enable() calls to invalid mutex lock magic numbers, workqueues not initialized and missing resume sequences.
In 'nominal' usages, there is no change of functionality, this is just a first step to test random device/driver bind/unbind sequences.
Important note: these changes only touch Intel-based platforms, I don't have any background and ability to test on Qualcomm-based devices.
