sctp: remove the typedef sctp_paramhdr_t
This patch is to remove the typedef sctp_paramhdr_t, and replace with struct sctp_paramhdr in the places where it's using this typedef. It is also to fix some indents and use sizeof(variable) instead of sizeof(type). Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
