The pca954x device do not have the ability to mask interrupts. For i2c slave devices that also don't have masking ability (eg ltc1760 smbalert output) delay registering the irq until after the mux segments have been configured. During the mux add_adaptor call the core i2c system can register an smbalert handler which would then be called immediately when the irq is registered. This smbalert handler will then clear the pending irq. This removes the need for the irq_mask / irq_unmask calls that were original used to do this.
