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. Set the IRQF_SHARED to be able to share the interrupt line with other devices.
