Calling component_add starts loading the firmware, the callback function writes the program to the amplifiers. If the module resets the amplifiers after component_add, it happens that one of the amplifiers does not work because the reset and program writing are interleaving. Call tas2781_reset before component_add to ensure reliable initialization.
