* drm_kunit_helper_alloc_drm_device - Allocates a mock DRM device for KUnit tests
* @_test: The test context object
* @_dev: The parent device object
* @_type: the type of the struct which contains struct &drm_device
* @_member: the name of the &drm_device within @_type.
* @_features: Mocked DRM device driver features
*
* This function creates a struct &drm_driver and will create a struct
* &drm_device from @_dev and that driver.
*
* @_dev should be allocated using drm_kunit_helper_alloc_device().
*
* The driver is tied to the @_test context and will get cleaned at the
* end of the test. The drm_device is allocated through
* devm_drm_dev_alloc() and will thus be freed through a device-managed
* resource.
*
* Returns:
* A pointer to the new drm_device, or an ERR_PTR() otherwise.
