Do I need to send another patch? The mail says " Rob's (experimental) review bot".
Previously for RZ/G1C upstreaming I have submitted the patches in similar fashion.
Is anything changed?

Yes, indeed.
At one point I was enforcing such a split but as it did not seem to be a
universal practice I stopped doing so. I'd like some clear guidance from
Rob if he'd like this split to occur going forwards.
As for this patch, I have applied it for v4.20.

I've generally not asked for either of these on 1 (or few) line
changes or if I had no other comments on the patch. But for automated
checking I'm not going to try to make that distinction. So, still up
to whomever applies them.
BTW, I'm adding the splitting patches check to checkpatch.pl too.

Thanks, it sounds to me that splitting things will be the cleanest
approach for future patches. We'll see how that goes.
