Does anyone on the greybus list know anything about this person:

Unsigned variables are printed using %d. Replace them with %u to match their types.

I have reviewed every one of these and they look good. Quite a few of them--because the size of the value being formatted is less than 32 bits--would print correctly no matter what their value. But I think it at least does no harm to convert the format specifier to unsigned in all of these cases.
I have highlighted below an existing bug that should be fixed. It gives an example of something to look for when you do this sort of activity. Please arrange to get that bug fixed.
I also pointed out one other observation for you to think about.
Thanks for sending this. I didn't check to find any other instances you might have missed, but you seem to have found quite a few.

This line actually contains an error (and it was there before).
The type of gb_bootrom_firmware_size_response->size is __le32. So the value being formatted needs to be converted into CPU byte order before being used. That could be done this way: le32_to_cpu(size_response->size) or just use this, which is known from a few lines above to have the proper value and byte order: bootrom->fw->size
Please add this to your list of things to fix, and submit it as a separate patch. This would be a bug fix, which would also give you a little bit of a new experience.

I don't think this needs to be changed necessarily, but it's something inconsistent across the Greybus code. Consistency helps readability and maintainability.
