[PATCH 09/24] drm/dev: Remove drm_dev_init

[Daniel Vetter <daniel.vetter@ffwll.ch>]

We can now also delete drm_dev_init, now that vkms, vgem and i915
selftests are resolved.

-/**
- * 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_get() and
- * drm_dev_put() to take and drop further ref-counts.
- *
- * It is recommended that drivers embed &struct drm_device into their own device
- * structure.
- *
- * Drivers that do not want to allocate their own device struct
- * embedding &struct drm_device can call drm_dev_alloc() instead. For drivers
- * that do embed &struct drm_device it must be placed first in the overall
- * structure, and the overall structure must be allocated using kmalloc(): The
- * drm core's release function unconditionally calls kfree() on the @dev pointer
- * when the final reference is released. To override this behaviour, and so
- * allow embedding of the drm_device inside the driver's device struct at an
- * arbitrary offset, you must supply a &drm_driver.release callback and control
- * the finalization explicitly.
- *
- * Note that drivers must call drmm_add_final_kfree() after this function has
- * completed successfully.
- *
- * RETURNS:
- * 0 on success, or error code on failure.
