(resending to add linux-crypto, patch unchanged) The min3() macro expects all arguments to be of the same type (or size at least). Change the type of some local variables in sun4i-ss-hash.c to size_t to match the type used in some generic structures we compare against. That shouldn't change anything for 32-bit (as size_t is unsigned int there anyway), but allows compilation for 64-bit architectures. There are two casts still necessary, because we can't change the type in a generic structure.
