std: work around current packed struct situation
As of 6249a24, align() is not allowed on packed struct fields
and as such the align(4) was removed from the first field of
EdidOverrideProtocolAttributes. The endgame here is packed struct
backed by explicit integers, in this case a u32, but until that
is implemented put the align(4) on the pointer to avoid breaking
someone's UEFI code in a hard to debug way.1 files changed, 9 insertions(+), 1 deletions(-)
