[IPV4]: [4/4] signed vs unsigned cleanup in net/ipv4/raw.c
This patch changes the type of the third parameter 'length' of the raw_send_hdrinc() function from 'int' to 'size_t'. This makes sense since this function is only ever called from one location, and the value passed as the third parameter in that location is itself of type size_t, so this makes the recieving functions parameter type match. Also, inside raw_send_hdrinc() the 'length' variable is used in comparisons with unsigned values and passed as parameter to functions expecting unsigned values (it's used in a single comparison with a signed value, but that one can never actually be negative so the patch also casts that one to size_t to stop gcc worrying, and it is passed in a single instance to memcpy_fromiovecend() which expects a signed int, but as far as I can see that's not a problem since the value of 'length' shouldn't ever exceed the value of a signed int).
