[PATCH 1/5] iio: adc: cc10001: Add local struct device *dev variable to avoid repitition

[Jonathan Cameron <jic23@xxxxxxxxxx>]

From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>

There are lots of uses of this in probe() and we are about to introduce
some more, so add a local variable to simplify this.
