All 64bit archs use unsigned long for size_t and most 32bit archs use 'unsigned int'. By default, this is what is assumed by sparse.
However, on h8300 (a 32bit arch) size_t is unsigned long which can led sparse to emit wrong warnings. Fix this by passing to sparse the flag -msize-long, telling it that size_t is unsigned long.
