charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the set_DAC macro with a static function named set_dac(). The helper has only one caller, so keep it local to ddk750_display.c and remove the macro from ddk750_power.h. This provides parameter type checking and follows kernel naming conventions without changing the register operation.
