+IPC_ENUM_TRAITS(content::InputEvent::Payload::Type)

IPC_ENUM_TRAITS() is deprecated; use IPC_ENUM_TRAITS_MAX_VALUE (or MIN) instead.

Done.

 IPC_ENUM_TRAITS(content::InputEventAckState)

[palmer, 2013/09/03 23:12:47]

Might as well change this one now, too.

[jdduke (slow), 2013/09/04 17:53:24]

Done.
