Well, a) need to cc the scsi list and b) how is this possible when
MODULE_DEVICE_TABLE() has an empty definition if MODULE isn't defined
(so the guard you move should be over an empty statement)?

Thanks Maxim! I'm still working on a respin of this t
ps don't need to have the logic for
is_guest_part()/is_host_part().
That leads me to wonder about updating the printout:
hw perfevents: enabled with armv8_pmuv3_0 PMU driver, 7 (0,803f)

It might be a bit confusing if that doesn't quite reflect reality anymore.
