The driver reuses the OF node of the parent multi-function device but fails to take another reference to balance the one dropped by the platform bus code when unbinding the MFD and deregistering the child devices.

The datasheet specifies, that the IRQ_B pin is pulled low when any unmasked interrupt bit status is changed, and it is released high once the application processor reads the INT1 register. As it specifies a level-low behavior, it should not force a falling-edge interrupt. Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt and instead rely on the flag from the device tree.
