I found that it seems to be because 5.13 newly introduced
"DT_CHECKER_FLAGS=-m", and I am still using the old
"make dt_binding_check" command, so this error is not prompted. Now I
can see this error message after using the
"make DT_CHECKER_FLAGS=-m dt_binding_check" command, and I will send a
fix soon.
Thanks and best regards!
