I tried to fix it by assigning the pointer of that new field to the groups field of sdev_gendev so the driver core gets our groups on devide_add(). Just like scsi_host_alloc() was changed by the same commit, although scsi_host_alloc() already had assigned something to shost_dev.groups so the necessary change was more obvious there.
Thanks for having reported this early. We probably need something like this (entirely untested):
