[-mm PATCH][2/4] net: signed vs unsigned cleanup in net/ipv4/raw.c

[Jesper Juhl <juhl-lkml@xxxxxx>]

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.
