I'm pretty sure I always had that enabled, and never had issues. Can't
test right now since I don't have that option back yet in the tree I'm
using.

I'm just contesting that that someone should be me. I don't think you
get to blame driver developers for doing something that worked and
solved the problem they needed to solve. sysfs is largely opaque to most
of us already, and it now sure feels like Kay decided to change the
rules underneath the code in saying "this was wrong all along".
