Do not give a warning for the eDP panels if the "bus_format" is not specified, since most eDP panels can support more than one bus formats and this can be auto-detected. Also, update the check to include bpc=10 for the eDP panel.

You'll still get a warning is bpc == 0, is that intentional ?
This was not intentional, I missed considering bpc=0 case. As we are removing the warning for bus_format=0 then a similar thing can be done for the bpc=0 also. The bpc value should be a valid one if it is specified. Unlike the bus_format, bpc has few possible values that can be checked here along with 0. Please correct me if I misunderstood the concept. I will fix this.
Thanks, Rajeev
