net/core: remove address space warnings on verify_iovec()
move_addr_to_kernel() and copy_from_user() requires their argument as __user pointer but were missing proper markups. Add it. This removes following warnings from sparse. net/core/iovec.c:44:52: warning: incorrect type in argument 1 (different address spaces) net/core/iovec.c:44:52: expected void [noderef] <asn:1>*uaddr net/core/iovec.c:44:52: got void *msg_name net/core/iovec.c:55:34: warning: incorrect type in argument 2 (different address spaces) net/core/iovec.c:55:34: expected void const [noderef] <asn:1>*from net/core/iovec.c:55:34: got struct iovec *msg_iov Signed-off-by: Namhyung Kim <namhyung@gmail.com> Signed-off-by: David S.
