dev_name() will be something like adc@12345678 from the devicetree,
so not the "part number".

This style is preferred if there is only one supported part.

We try to avoid using a macro for the driver name like this.

Looks like we missed catching this one in review.

This is preferred if there is more than one part supported in the driver.

This is fine too in cases where there isn't chip_info.

That works.
