[IPV4]: [2/4] signed vs unsigned cleanup in net/ipv4/raw.c
This patch gets rid of the following gcc -W warning in net/ipv4/raw.c :
net/ipv4/raw.c:387: warning: comparison of unsigned expression < 0 is always false
Since 'len' is of type size_t it is unsigned and can thus never be <0, and
since this is obvious from the function declaration just a few lines above
I think it's ok to remove the pointless check for len<0.
