I noticed that there is a prototype for vmw_fifo_ping_host_locked() but
no function. Then I looked further and noticed more functions which are
not used anymore or functions protoypes which remained after the
function was removed.
Remove unused function (prototypes).

vmw_fifo_ping_host() disables preemption around a test and a register
write via vmw_write(). The write function acquires a spinlock_t typed
lock which is not allowed in a preempt_disable()ed section on
PREEMPT_RT. This has been reported in the bugzilla.
It has been explained by Thomas Hellstrom that this preempt_disable()ed
section is not required for correctness.
Remove the preempt_disable() section.

TTM doesn't yet fully support mapping of DMA memory when SEV is active,
so in that case, refuse DMA operation. For guest-backed object operation
this means 3D acceleration will be disabled. For host-backed, VRAM will be
used for data transfer between the guest and the device.

When we refuse DMA from system pages for whatever reason, we don't
handle that correctly when guest-backed objects was enabled.
Since guest-backed objects by definition require DMA to and from
system pages, disable all functionality that relies on them.
That basically amounts to 3D acceleration and screen targets.

For example if the target-node is in the disabled state, so no

In that case current code would count that as external rgb device,
which in turn would make probing the rockchip-drm device fail.
So only count the target as rgb device if the function actually

i915 can enable aux device nodes for DP MST by calling
drm_dp_mst_connector_late_register()/
drm_dp_mst_connector_early_unregister(),
so let's hook that up.
Changes since v1:
* Call intel_connector_register/unregister() from
intel_dp_mst_connector_late_register/unregister() so we don't lose
error injection - Ville Syrjälä
Changes since v2:
* Don't forget to clean up if intel_connector_register() fails - Ville
