When CONFIG_SND=m and CONFIG_SND_AC97_CODEC=m and
CONFIG_VIDEO_STK1160=y
CONFIG_VIDEO_STK1160_AC97=y

drivers/built-in.o: In function `stk1160_ac97_register':

This kconfig fragment:
config VIDEO_STK1160_AC97
	bool "STK1160 AC97 codec support"
	depends on VIDEO_STK1160 && SND
	select SND_AC97_CODEC

is unreliable (doesn't do what some people expect) when SND=m and SND_AC97_CODEC=m,
since VIDEO_STK1160_AC97 is a bool.
