caif: fix a signedness bug in cfpkt_iterate()
The cfpkt_iterate() function can return -EPROTO on error, but the function is a u16 so the negative value gets truncated to a positive unsigned short. This causes a static checker warning. The only caller which might care is cffrml_receive(), when it's checking the frame checksum. I modified cffrml_receive() so that it never says -EPROTO is a valid checksum. Also this isn't ever going to be inlined so I removed the "inline". Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
