When CONFIG_SCSI_LPFC_DEBUG_FS is unset, uuid's declaration is not present, resulting in a compiler error: drivers/scsi/lpfc/lpfc_scsi.c:5595:3: error: use of undeclared identifier 'uuid' uuid = lpfc_is_command_vm_io(cmnd); ^ uuid is only used in the if statement so reduce its scope to solve the build error. Additionally, uuid is a char *, instead of u8 *.
