Nope. The driver you were referring to does the same you did.

I'm proposing the above struct to be introduced along with changing
prototype like:

 -int adxl345_core_probe(struct device *dev, struct regmap *regmap,
const char *name);
 +int adxl345_core_probe(struct adxl345_chip *chip);

In next patch adding interrupt would not touch prototypes at all!

I suppose something like platform_get_irq(); to use.
But it would be nice to you to investigate more.
