From: Xin Long Date: Fri, 30 Jun 2017 03:52:12 +0000 (+0800) Subject: sctp: remove the typedef sctp_sctphdr_t X-Git-Tag: MMI-PSA29.97-13-9~5285^2~46^2~10 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ae146d9b76589d636d11c5e4382bbba2fe8bdb9b;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git sctp: remove the typedef sctp_sctphdr_t This patch is to remove the typedef sctp_sctphdr_t, and replace with struct sctphdr 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 Signed-off-by: David S.
