Subject: [PATCH] staging: slicoss.ko: slicoss.c: Fixed incorrect argument type

sparse produced
warning: incorrect type in argument 2 (different address spaces)
expected void const volatile [noderef] <asn:2>*src
got struct slic_stats *stats

casting argument 2 to what is expected by memcpy_fromio() fixed this
