From: Marc CAPDEVILLE
Date: Mon Dec 25 2017 - 10:58:19 EST


Somme cosmetic cleanup suggested by Peter Meerwald-Stadler.

Macro name :
MLUX_PER_LUX => CM32181_MLUX_PER_LUX

Constante name :
als_it_bits => cm32181_als_it_bits
als_it_value => cm32181_als_it_value

Comment :
Registers Address => Register Addresses
