[ Upstream commit dc19fa63ad80a636fdbc1a02153d1ab140cb901f ]
The ms5611 passes &indio_dev->dev as a parameter to all its IO callbacks only to directly cast the struct device back to struct iio_dev. And the struct iio_dev is then only used to get the drivers state struct.
Simplify this a bit by passing the state struct directly. This makes it a bit easier to follow what the code is doing.
