I must think about this, I think.
A quick look at joy.ko shows that the following symbols are undefined:
U card_compat_attach_desc
U card_compat_do_attach_desc
U card_compat_do_probe_desc
U card_compat_match_desc
U card_compat_probe_desc
U isa_pnp_probe_desc
ed shows a similar list of undefined symbols.
There are two cases here. Some of these symbols come from using an
interface, while others come from implementing that interface.
Maybe we do need to compile all the *_if.c files into the kernel, used
or not, to allow any driver to be loaded. If the bus isn't there,
then it will not probe on that bus, but there won't be the unresolved
symbols.
I'm unsure. Comments?
Warner
BTM, here's a patch to implement all *_if.c files vs current. This
should help the original poster around his problem.
