    iio: inkern: add error case in iio_channel_get() · b2b79ffa
    Kim, Milo authored
     The datasheet name is defined in the IIO driver.
     On the other hand, the adc_channel_label is configured in
     the platform side.
     If the datasheet name is not matched with any adc_channel_label,
     the iio_channel_get() should be returned as error for preventing
     invalid channel data access.
    
     This can be handled either way.
     (a) checking null data when using it : in the xxx_read_raw()
     or
     (b) error returns when the channel is requested : this patch
    
     The IIO consumer can't use the channel with invalid channel spec.
     Therefore case (b) is more reasonable.
