This one is only set and never read. A name is probably enough.

Ok, I'll remove model.

This one should be a local variable.

Ok, I'll move it to the func where it's used.

How does it differ from fbdev->panel? Is it duplicated field?

fbdev->panel is a pointer to this device instance specific data. It's embedded here
so that we can get to struct mipid_device with the container_of macro when fbdev->panel
is passed to us.

I am sorry but I had not enough time to review the rest.

Thanks for the review, if there is nothing else I can post a new version with the
above changes.
