If the driver is unbound whilst the jack is still inserted this will cause warnings from the regulator framework as the MICVDD regulator is put but was never disabled. Correct this by disabling microphone detection on driver removal and if the microphone detection was running disable the regulator and put the runtime reference that was currently held.
