If Ok, I would prefer to keep this here, as there's no other cleanups
anymore, and writing a patch just for this seems overkill. Besides,
it replicates a comment with a similar content on this patch.
So, instead, if OK to you, I would prefer to add a comment about it at
the patch description.

Changed this one to uint32_t.

Good to know. That's my personal style too. Yet, I guess I saw somewhere
other places declaring variables in the middle of the code.
