Export ibmvfc_debug so the NVMe support code can use the existing ibmvfc_dbg logging macro. The debug control variable is currently file-local to the core driver, which prevents protocol-specific code in ibmvfc-nvme.c from using the shared debug infrastructure. Make the variable global within the module and declare it in ibmvfc-nvme.h.
