clang points out that ret in ks8851_read_selftest() is set but unused:
drivers/net/ethernet/micrel/ks8851_common.c:1028:6: warning: variable
'ret' set but not used [-Wunused-but-set-variable]
int ret = 0;
^
1 warning generated.
The return code of this function has never been checked so just remove
ret and make the function return void.
