Hmm, maybe it would be nice to introduce that capability. How doable
would it be? I understand the BKL is going away, perhaps it would now be
easier to introduce such a facility?
I've just started digging into the innards of the s3fb driver, my first
attempt provoked this, simply by commenting out the check to see if it's
not the primary device and exits with -ENODEV:
