Hi,

Sorry, the delay in taking a look at this patch.

I tried to find the whole series for getting the context related to this
patch, but I could not find it in my mailbox. Could you shed some light
here? Why check fb and crtc is too much? How the WARN_ON fix the issue?

Best Regards

Ps.: in the commit message: "stope" -> "stop"
