  * drm_gem_shmem_mmap - Memory-map a shmem GEM object
- * @filp: File object
+ * @obj: gem object
  * @vma: VMA for the area to be mapped
  *
  * This function implements an augmented version of the GEM DRM file mmap
  * operation for shmem objects. Drivers which employ the shmem helpers should
- * use this function as their &file_operations.mmap handler in the DRM device file's
- * file_operations structure.
- *
- * Instead of directly referencing this function, drivers should use the
- * DEFINE_DRM_GEM_SHMEM_FOPS() macro.
+ * use this function as their &drm_gem_object_funcs.mmap handler.
  *
  * Returns:
  * 0 on success or a negative error code on failure.
