Subject: mctp: Be explicit about struct sockaddr_mctp padding
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a20dd46b8b8459382685969cf0f196ae9fb9766;p=linux.git

mctp: Be explicit about struct sockaddr_mctp padding

We currently have some implicit padding in struct sockaddr_mctp. This
patch makes this padding explicit, and ensures we have consistent
layout on platforms with <32bit alignmnent.

Fixes: 60fc63981693 ("mctp: Add sockaddr_mctp to uapi")
