Thank you for the update!

No need to change here.

Also I'm not sure about "}, {" style. Lee as the maintainer can clarify
on this.

I would preserve reversed xmas tree order:

	const struct intel_lpss_platform_info *data = (void *)id->driver_data;
	const struct pci_device_id *quirk_pci_info;
	struct intel_lpss_platform_info *info;
	int ret;

Can you confirm that there is no compiler warning if you compile for 32-bit?

Please, mind the periods at the ends of sentences.

Depending on the above (32-bit compilation) this might be converted to
unsigned long.
