Sorry for the delay.

Now I sent out the fix for lantiq_etop.c

https://lore.kernel.org/patchwork/patch/1355595/


The reason of the complication was
I was trying to merge the following patch in the same development cycle:
https://patchwork.kernel.org/project/linux-kbuild/patch/20201117104736.24997-1-olaf@xxxxxxxxx/


-Werror=return-type gives a bigger impact
because any instance of __must_check violation
results in build breakage.
So, I just dropped it from my tree (and, I will aim for 5.12).

The removal of CONFIG_ENABLE_MUST_CHECK is less impactive,
because we are still able to build with some warnings.


Tomorrow's linux-next should be OK
and, you can send my patch in this merge window.
