Yes, that's exactly it.

Ok, sounds like a plan.

fieldbus_dev is a new subsystem.
At first I attempted to mainline the anybus-s drivers with a 'roll-your-own'
userspace API, but the feedback I got was: this userspace API should
really be generic... So this is my attempt to create a generic fieldbus_dev
API !

It's almost certainly insufficient, but it's a start. Ideally, this
should get lots
of review from people in the industry, but response to this patchset has
been underwhelming. That's the reason this is going into staging/.
Hopefully it will create discussion, and a way forward to a more extensive
userspace API. If not, it'll go to /dev/null after a year.
