That means a superfluous cast is removed and aliasing through a uint8_t pointer is eliminated. NB: The C standard specifies that a unsigned char pointer may alias while the C standard doesn't include such requirement for uint8_t pointers. Also simplified the loop since a modern C compiler can speed up (i.e. auto-vectorize) it in a similar way. For example, GCC auto-vectorizes it for Haswell using AVX registers while halving the number of instructions in the generated code.
