It in not uncommon for code to use min_t(uint, a, b) when one of a or b is 64bit and can have a value that is larger than 2^32; This is particularly prevelant with: uint_var = min_t(uint, uint_var, uint64_expression); Casts to u8 and u16 are very likely to discard significant bits. [...]
Applied, thanks!
[12/44] block: use min() instead of min_t()
