Could you please split this in different patches? Add id in one
patch and refactor in a different patch. Please, also the
refactorings need to be split.

I see here that this is a general code cleanup, plus some other
stuff.

you don't need the cast here... if you don't find it messy, I
wouldn't mind this form... some hate it, I find it easier to
read:

	chip_info = spi_get_device_id(spi)->driver_data;

your choice.
