Arguably, there are more chances of errors occurring during the initialization of the hardware, so this should complete successfully before the devicetree node's children are initialized. st1202_dt_init() fills the led_classdev struct. st1202_setup() initializes the hardware. Specifically, resets the chip, enables its phase-shift delay feature, enables the device and disables all the LEDs channels. All that writing to registers, with no input from st1202_dt_init(). Real-world testing corroborates that calling st1202_setup() before st1202_dt_init() doesn't cause any issue during initialization. Switch the order of st1202_dt_init() and st1202_setup() to ensure the hardware is correctly initialized before the led_classdev struct is filled.
