Vim3l debian kernel 4.9, bootup fail after changes I made, need understand failure reason

I have been I was working to add my own lcd before than lcd support was turned off. here logs just before kernel panic starts. I reverted back all my changes in all repo to previous working commit rebuilt image again but still no effects.

I just want to know what this error is saying. so I can find and remove this pesky bug in some configuration.
