The format for the function name/description uses '-', not ':', as:

+ * @xattrs: simple_xattr list
+ * @name: name of the new extended attribute
+ * @value: value of the new extended attribute. If NULL, will remove the
+ *	   attribute

Missing @size parameter description.

+ * @flags: if XATTR_CREATE is set, no already existing extended attribute may
+ *	   exist. If XATTR_REPLACE is set, the extended attribute should exist.
+ *
+ * returns -ENOMEM for allocation failures, -EEXIST in case XATTR_CREATE is
+ *	   set in flags and an extended attribute with the same name exists,
+ *	   -ENODATA if XATTR_REPLACE is set in flags but no entry with the
