When CONFIG_SND_SOC_HDAC_HDMI is disabled, we can run into an
uninitialized variable:
sound/soc/intel/skylake/skl.c: In function 'skl_resume':
sound/soc/intel/skylake/skl.c:326:6: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I have run into this on today's linux-next kernel, but it appears
that this is an older problem that was just hard to trigger
with randconfig builds as CONFIG_SND_SOC_HDAC_HDMI would in
effect be impossible to disable when having SND_SOC_INTEL_SKYLAKE
enabled.
