Hi,

I am seeing below build failure with latest linux-next repo.

Description:

Building the kernel with CONFIG_SCSI_IBMVFC=y and CONFIG_NVME_FC=m results in
a link failure when building vmlinux:

Build failure logs:

ld: drivers/scsi/ibmvscsi/ibmvfc-nvme.o: in function
`ibmvfc_nvme_register_remoteport':

Below simple check in Kconfig fixes the build failure.

If this is acceptable, then I will send a formal patch.

Yep, need to force ibmvfc to be a module when NVME_FC isn't builtin, or NVME_FC
must be disabled.
