If the initialisation fails, we may be left with a dangling pointer with
an incomplete fbdev structure. Here we want to disable internal calls
into fbdev. Similarly, the initialisation may be slow and we haven't yet
enabled the fbdev (e.g. quick suspend or last-close before the async init
completes

This shouldn't happen with 4.5, the fbdev is now clobbered if initialization
fails, the existing "if (dev_priv->fbdev)" che
If the initialisation fails, we may be left with a dangling pointer with
an incomplete fbdev structure. Here we want to disable internal calls
into fbdev. Similarly, the initialisation may be slow and we haven't yet
