Subject: [PATCH] drm/rockchip: inno-hdmi: Fix infoframe upload
HDMI analyser shows that the AVI infoframe is no being longer send.
The switch to the HDMI connector api should have used the frame content
which is now given in the buffer parameter, but instead still uses the
(now) empty and superfluous packed_frame variable.
Fix it.
