config SOUNDWIRE_QCOM
	tristate "Qualcomm SoundWire Master driver"
	imply SLIMBUS
	depends on SND_SOC

The kernel config that was attached has:
CONFIG_SOUNDWIRE_QCOM=y
CONFIG_SLIMBUS=m

I expected that "imply" would make SLIMBUS=y since SOUNDWIRE_QCOM=y,
but I guess that's not the case. :(

Any ideas about what to do here?
