inet6: Conversion from u8 to int
This replaces assignments of the type "int on LHS" = "u8 on RHS" with simpler code. The LHS can express all of the unsigned right hand side values, hence the assigned value can not be negative. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
