259 * drm_kunit_helper_create_primary_plane - Creates a mock primary plane for a KUnit test
260 * @test: The test context object
261 * @drm: The device to alloc the plane for
262 * @funcs: Callbacks for the new plane. Optional.
263 * @helper_funcs: Helpers callbacks for the new plane. Optional.
264 * @formats: array of supported formats (DRM_FORMAT\_\*). Optional.
265 * @format_count: number of elements in @formats
266 * @modifiers: array of struct drm_format modifiers terminated by
267 * DRM_FORMAT_MOD_INVALID. Optional.
268 *
269 * This allocates and initializes a mock struct &drm_plane meant to be
270 * part of a mock device for a KUnit test.
271 *
272 * Resources will be cleaned up automatically.
273 *
274 * @funcs will default to the default helpers implementations.
275 * @helper_funcs will default to an empty implementation. @formats will
276 * default to XRGB8888 only. @modifiers will default to a linear
277 * modifier only.
278 *
279 * Returns:
280 * A pointer to the new plane, or an ERR_PTR() otherwise.
