The earlier version from linux-next-20170310 (there was no linux-next last week) had the same bug but needed a different workaround: diff --git a/drivers/scsi/Kconfig b/drivers/scsi/Kconfig index 4bf55b5d78be..52245eb83295 100644 --- a/drivers/scsi/Kconfig +++ b/drivers/scsi/Kconfig @@ -1256,12 +1256,14 @@ config SCSI_LPFC_DEBUG_FS config LPFC_NVME_INITIATOR bool "Emulex LightPulse Fibre Channel NVME Initiator Support" depends on SCSI_LPFC && NVME_FC + depends on SCSI_LPFC=m || NVME_FC=y ---help--- This enables NVME Initiator support in the Emulex lpfc driver. config LPFC_NVME_TARGET bool "Emulex LightPulse Fibre Channel NVME Initiator Support" depends on SCSI_LPFC && NVME_TARGET_FC + depends on SCSI_LPFC=m || NVME_TARGET_FC=y ---help--- This enables NVME Target support in the Emulex lpfc driver.
