Interesting. No devicetree bindings for this one? What kind of
system is it on?

Currently, the driver sets `indio_dev->name = AM2315_DRIVER_NAME;`
Usually, when there is more than one chip supported in a driver, we
want this to be the the name of the actual chip.

(And we usually try to avoid DRIVER_NAME macros so removing that
would be a welcome change.)
