The function that I am missing (release_firmware) is compiled into
lib/lib.a. and shows up in lib.a.flags. But it does not show up in vmlinux
binary or the symbol table. I couldn't see that the generic Malta make
file has any garbage collection on but I can't see where it is lost.
What I get is unresolved symbols when I insmod my driver.
Any ideas from the experts?

It's a library so if no reference is preceeding the library that member
won't be linked in.

And to be usable by a module, you have to make sure the symbol is exported by
the kernel using EXPORT_SYMBOL().

For the mips architecture, it seems like arch/mips/lib/lib.a is linked in
and not lib/lib.a. For example on menuconfig when zlib* is selected, it is
not included in the final link. Is my understanding correct? Specifically,
2.4.23 has a firmware library (from lib/) that I would like to use with a
driver but regardless of my .config it is not being linked.
Thanks for your help.
