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.
