This just happens to work because the value of MAX77686_OPMODE_MASK (0x3) is also "Output ON in Normal Mode" but the code is not correct IMHO. Or even better, the regulator mode should be read from the hw registers instead of setting always to normal. That is what the max77802 driver does for example.
