Merge branch 'nvme-4.12' of git://git.infradead.org/nvme into for-4.12/post-merge

Christoph writes:

"A couple more updates for 4.12.  The biggest pile is fc and lpfc
 updates from James, but there are various small fixes and cleanups as
 well."

Fixes up a few merge issues, and also a warning in
lpfc_nvmet_rcv_unsol_abort() if CONFIG_NVME_TARGET_FC isn't enabled.
