    iio: adc: ti-ads1015: remove unnecessary config register update · 56b57a9e
    Akinobu Mita authored
    The ti-ads1015 driver has eight iio voltage channels and each iio channel
    can hold own scale information.
    
    The ADS1015 device only have a single config register which contains an
    input multiplexer selection, PGA and data rate settings.  So the driver
    should load the correct settings when the input multiplexer selection is
    changed.
    
    However, regardless of which channlel is currently selected, changing any
    iio channel's scale information immediately overwrites the current PGA
    setting in the config register.
    
    It is harmless because the correct PGA settings are reloaded just before
    getting adc result anyway.  But it is unnecessary register update and
    should be removed.
