CAPDEVILLE Marc Jan. 13, 2018, 1:37 p.m. UTC 
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
