Browse Source 
PD#SWPL-18673

Problem:
when hotplug cable very quickly, the pin contact may
be loose and edid read wrong, system will output
default 1080p+rgb signal, after the pin contact
ok and edid read ok, DV module send DV signal, the
output mode and DV signal may not match, cause
TV show green screen.

Solution:
only attach vinfo after hdmi mode setting done.
