2019-04-22iio: imx7d_adc: Simplify imx7d_adc_remove() with imx7d_adc_suspend()Andrey Smirnov
Since imx7d_adc_remove() does exactly the same thing as imx7d_adc_suspend() we can use the latter together with devm_add_action_or_reset() to simplify the former. Rename imx7d_adc_suspend() to imx7d_adc_disable() for clarity while at it.

2019-04-22iio: imx7d_adc: Simplify imx7d_adc_probe() with imx7d_adc_resume()Andrey Smirnov
Initialization sequence performed in imx7d_adc_resume() is exactly the same as the one being done in imx7d_adc_probe(). Make use of the former in the latter to avoid code duplication. Rename imx7d_adc_resume() to imx7d_adc_enable() for clarity while at it.
