[Qemu-devel] [PATCH v2 06/16] hw/display/xlnx_dp: Move problematic code from instance_init to realize

[Thomas Huth <thuth@redhat.com>]

aux_create_slave() calls qdev_init_nofail() which in turn "realizes"
the corresponding object. Thus this most not be called from an
instance_init function. Move the code to the realize function instead.
