Sorry for the delay. I gave this a spin on my Juno. I am seeing below
warning once on boot but it continues and everything seem to work fine.
Also the warning is not related to this change I believe and this patch
is just helping to hit some corner case with deferred probe and devres.
I need to spend some time to debug it.
