Hello,
When using vsscanf to convert string to int, it uses simple_strtol, and it fails to convert if the string is longer then 16 bytes. 


Example code:

const char hexstring[] = "deadbeef10203040b0", *pos = hexstring;
unsigned char val[9];
size_t count = 0;

for(count = 0; count < sizeof(val)/sizeof(val[0]); count++) {
	sscanf(pos, "%2hhx", &val[count]);
	pos += 2;
}

/* val will be 00adbeef10203040b0 instead of deadbeef10203040b0. */

Thank you
