 nvmet: adding nsid 1 to subsystem blktests-subsystem-1
 nvmet: creating controller 1 for subsystem blktests-subsystem-1 for NQN nqn.2014-08.org.nvmexpress:uu.
 nvme-fabrics ctl: DEVRES ADD 000000009bc92dfd devm_kzalloc_release (552 bytes)
 nvme-fabrics ctl: DEVRES ADD 0000000099e1e156 devm_hwmon_release (8 bytes)

I've enabled CONFIG_DEVRES_DEBUG and see only 'DEVRES ADD' message. If I
read it correctly the problem is that the resource is attached to the ctl
devm object and not for the nvme devm object.
