  To: dri-devel; +Cc: intel-gfx, Rodrigo Vivi

The commit below returned earlier than before, but failed to move the
info message when authenticating without downstream devices. This patch
restores the message on authentication success.

Fixes: 87eb3ec818fa ("drm/i915: II stage HDCP auth for repeater only")
