This looks like it is preserving this userspace-sensitive semantic so that dynamically added chips will still get the same assigned numbers.
It does (it should, at least), the assigned ranges should be strictly identical to the previous version. While testing I also made sure all chips had the same GPIO range.
But I want some guarantees, so state clearly in the commit that any dynamically assigned chip will get the same base address after this change as it got before it, and please take this opportunity to add a comment stating that this search method is vital for userspace ABIs, and must be preserved.
Done. I will take the blame if something goes wrong. :) Thanks, Alex. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
