From 1274045b0eda1df5a5cdd3e63ed48cf013b3b4ea Mon Sep 17 00:00:00 2001 From: Venkat Rao Bagalkote Date: Thu, 3 Sep 2026 13:13:29 +0530 Subject: [PATCH] scsi: ibmvfc: Add Kconfig dependency to fix link failure when NVME_FC=m Building with CONFIG_SCSI_IBMVFC=y and CONFIG_NVME_FC=m results in a link failure: ibmvfc-nvme.o: undefined reference to `nvme_fc_register_localport' ibmvfc-nvme.o: undefined reference to `nvme_fc_register_remoteport' ibmvfc-nvme.o: undefined reference to `nvme_fc_unregister_localport' ibmvfc-nvme.o: undefined reference to `nvme_fc_unregister_remoteport' ibmvfc-core.o: undefined reference to `nvme_fc_rescan_remoteport' IS_ENABLED() evaluates to 1 for both =y and =m, so the nvme_fc_* call sites are kept in the object file. When SCSI_IBMVFC=y (built-in) but NVME_FC=m (loadable module), the linker cannot resolve these symbols at vmlinux link time. Add the same "depends on NVME_FC || NVME_FC=n" constraint already used by SCSI_LPFC to prevent this configuration.
