The pending irq work might be still floating while the assigned stream has been already closed, which may lead to UAF, especially when another async work for fasync is involved. For addressing this, extend the hda_controller_ops for allowing the extra cleanup procedure that is specific to the controller driver, and make sure to cancel and sync the pending irq work at each PCM close before releasing the resources.
