# HG changeset patch
# User Ian Campbell <ian.campbell@xxxxxxxxxx>
# Date 1302276980 -3600
# Node ID 1ac49d2c7d7012c27435e78706b03272cf708efc
# Parent 892e611b47d89bf351430a0e8015fd9c9061a431
libxl: drop domid field from libxl_device_*
All functions which add a device to a domain already take a domid
argument and the callers typically write the same value to the
structure right before making the call.
Functions which delete a device typically do not but adding this field
makes the interface more consistent anyway and all callers have the
domid to hand.
All functions which return a libxl device structure are given a domid
as a paramter and the caller therefore already knows which domain it
is dealing with.
