* amdgpu_dm_atomic_check() - Atomic check implementation for AMDgpu DM.
* @dev: The DRM device
* @state: The atomic state to commit
*
* Validate that the given atomic state is programmable by DC into hardware.
* This involves constructing a &struct dc_state reflecting the new hardware
* state we wish to commit, then querying DC to see if it is programmable. It's
* important not to modify the existing DC state. Otherwise, atomic_check
* may unexpectedly commit hardware changes.
*
* When validating the DC state, it's important that the right locks are
* acquired. For full updates case which removes/adds/updates streams on one
* CRTC while flipping on another CRTC, acquiring global lock will guarantee
* that any such full update commit will wait for completion of any outstanding
* flip using DRMs synchronization events.
*
* Note that DM adds the affected connectors for all CRTCs in state, when that
* might not seem necessary. This is because DC stream creation requires the
* DC sink, which is tied to the DRM connector state. Cleaning this up should
* be possible but non-trivial - a possible TODO item.
*
* Return: -Error code if validation failed.
