I am trying to make sense of drivers/sgi/char/Makefile in 2.4.4-pre5. export-objs := newport.o shmiq.o sgicons.o usema.o obj-y := newport.o shmiq.o sgicons.o usema.o streamable.o obj-$(CONFIG_SGI_SERIAL) += sgiserial.o obj-$(CONFIG_SGI_DS1286) += ds1286.o obj-$(CONFIG_SGI_NEWPORT_GFX) += graphics.o rrm.o None of newport.o shmiq.o sgicons.o usema.o export any symbols so why are they defined as export-objs? The only object that does export symbols is graphics_syms.c and no Makefile refers to that source, it appears to be dead. I recommend removing all export-objs from drivers/sgi/char/Makefile and deleting drivers/sgi/char/graphics_syms.c.
