There's a problem when compiling the GUS driver into the kernel
instead of as a module. I renamed the global "lock" to "gus_lock"
and made sure that it's used (shared by gus_midi, gus_wave, ics2101)

[snippet of sound/oss/Makefile]
obj-$(CONFIG_SOUND_GUS)         += gus.o ad1848.o
gus-objs        := gus_card.o gus_midi.o gus_vol.o gus_wave.o ics2101.o


Adrian: Do you have a GUS and can test this?
