With GuC handling scheduling, i915 is not aware of the time that a

We currently do an explicit flush of the buffer pools within the call path
of drm_driver.release(); this removes all buffers, regardless of their age,
freeing the buffers' associated resources (objects, adress space areas).
However there is other code that runs within the drm_driver.release() call

Even though we already check that the encoder->crtc pointer is there
during in startup(), which is part of the open() path in ASoC, nothing
guarantees that our encoder state won't change between the time when we
open the device and the time we prepare it.
Move the sanity checks we do in startup()
The drm_encoder crtc pointer isn't really fit for an atomic driver,
let's rely on the connector state instead.

patch series is about.
