there are cases that LVDS supports EDID but VBT is wrong.. why not use a flag in private structure to set that, if first take of reading EDID has been failed, we won't bother to read EDID again? nobody is able to hotplug a LVDS panel anyway :)
Even though , the problem is more likely because a buggy user space tool that keep asking for EDID...
