The awacs sound driver produces a false-positive warning in ppc64_defconfig: sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': include/sound/control.h:219:9: warning: 'master_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] I haven't come up with a good way to rewrite the code to avoid the warning, so here is a bad one: I initialize the variable before the conditionall initialization so gcc no longer has to worry about it.
