Review comment:
I might be a bit out of context (I think you already worked on similar
changes in other PRs) but what is the motivation behind this change? I
understand that since you know which platform you are in you already now that
unsigned int is 32 bit, so no need to explicitly say so. However, aren't we
then introducing inconsistent practices in the code? Right now uint32_t is used
everywhere and it would be wrong to see some functions use one type and others
another type (regardless of actually being the same size).
Also, why is uint32_t a problem? Isn't this definition standard? (defined in
stdint.h after all)
