/**
* drm_dev_init - Initialise new DRM device
* @dev: DRM device
* @driver: DRM driver
* @parent: Parent device object
*
* Initialize a new DRM device. No device registration is done.
* Call drm_dev_register() to advertice the device to user space and register it
* with other core subsystems. This should be done last in the device
* initialization sequence to make sure userspace can't access an inconsistent
* state.
*
* The initial ref-count of the object is 1. Use drm_dev_ref() and
* drm_dev_unref() to take and drop further ref-counts.
*
* Note that for purely virtual devices @parent can be NULL.
*
* Drivers that do not want to allocate their own device struct
* embedding struct &drm_device can call drm_dev_alloc() instead.
*
* RETURNS:
* 0 on success, or error code on failure.
