The newly introduced device_for_each_child_reverse() would be used when MFD core removes the device. After this patch applied the devices will be removed in a reversed order. This behaviour is useful when devices have implicit dependency on order, i.e. consider MFD device with serial bus controller, such as SPI, and DMA IP that is attached to serial bus controller: before remove the DMA driver we have to be ensured that no DMA transfers is ongoing and the requested channel are unused.
