As we know, typedef is suggested not to use in kernel, even checkpatch.pl
also gives warnings about it. Now sctp is using it for many structures.
All this kind of typedef's using should be removed. This patchset is the
part 4 to remove it for another 14 basic structures from linux/sctp.h.
After this patchset, all typedefs are cleaned in linux/sctp.h.
Just as the part 1-3, No any code's logic would be changed in these patches,
only cleaning up.
Xin Long (14):
sctp: remove the typedef sctp_shutdownhdr_t
sctp: fix the name of struct sctp_shutdown_chunk_t
sctp: remove the typedef sctp_errhdr_t
sctp: remove the typedef sctp_operr_chunk_t
sctp: remove the typedef sctp_error_t
sctp: remove the typedef sctp_ecnehdr_t
sctp: remove the typedef sctp_ecne_chunk_t
sctp: remove the typedef sctp_cwrhdr_t
sctp: remove the typedef sctp_cwr_chunk_t
sctp: remove the typedef sctp_addip_param_t
sctp: remove the typedef sctp_addiphdr_t
sctp: remove the typedef sctp_addip_chunk_t
sctp: remove the typedef sctp_authhdr_t

This patch is to remove the typedef sctp_shutdownhdr_t, and
replace with struct sctp_shutdownhdr in the places where it's
using this typedef.
It is also to use sizeof(variable) instead of sizeof(type).

This patch is to fix the name of struct sctp_shutdown_chunk_t
, replace with struct sctp_initack_chunk in the places where
it's using it.
It is also to fix some indent problem.

This patch is to remove the typedef sctp_addiphdr_t, and
replace with struct sctp_addiphdr in the places where it's
using this typedef.
It is also to use sizeof(variable) instead of sizeof(type).
