As reported by the kernel test robot, the following warnings occur:
>> drivers/firmware/efi/sysfb_efi.c:331:39: warning: 'efifb_fwnode_ops' defined but not used [-Wunused-const-variable=]
331 | static const struct fwnode_operations efifb_fwnode_ops = {

190 | static const struct dmi_system_id efifb_dmi_system_table[] __initconst = {
| ^~~~~~~~~~~~~~~~~~~~~~
Unused variables, functions, and macro are conditionally compiled under
CONFIG_EFI. This includes 'efifb_fwnode_ops',
'efifb_dmi_swap_width_height[]', 'efifb_dmi_system_table[]',
'efifb_add_links', 'find_pci_overlap_node','efifb_set_system',
'efifb_overlaps_pci_range', and the 'EFIFB_DMI_SYSTEM_ID' macro.
Suppress unused symbol warnings and ensure inclusion only in relevant
configurations.
