I understand that the solution should be fixing the pci-j721e.c driver
rather than updating Kconfig or Makefile. Thank you for the feedback. I
will update the pci-j721e.c driver to handle the case that is triggering
the build error.

Ok, thanks!

I think a single if(IS_ENABLED(CONFIG_PCI_J721E_HOST)) check
is probably enough to avoid the link failure

but you may want to split it up further to get better dead
code elimination and prevent similar bugs from reappearing when
another call gets added without this type of check.

If you split j721e_pcie_driver into a host and an ep driver
structure with their own probe/remove callbacks, you can
move the IS_ENABLED() check all the way into module_init()
function.
