> Even without enabling the ringbuffers to allow command execution, we can still
> control the display engines to enable modesetting. So make the ringbuffer
> initialization failure soft, and mark the GPU as wedged instead.
> 
> v2: Only treat an EIO from ring initialisation as a soft failure, and abort module
> load for any other failure, such as allocation failures.
> 
> v3: Add an *ERROR* prior to declaring the GPU wedged so that it stands out
> like a sore thumb in the logs
