I have updated a custom VME device driver (mainly based on vme_user.c)
to 4.9 (previously it was for 3.14-).
I see that VME device drivers cannot be loaded and unloaded due to this

vme: make core vme support explicitly non-modular
In fact, this drops the remove function, that scans all devices attached
to the bus and call their remove function.
That means that "remove" entry points in VME device driver (let see in
drivers/staging/vme/devices/vme_user.c) are now dead code and the
required cleanup code is not called at all (devices and class are not
removed). Reloading the same driver cause errors due to the missing
cleanup by unloading. This does not let build VME device drivers as
module, as it is supposed to be done.
Paul, what do you mind ?
