Is it a really correct fix?
It looks like that this forces CONFIG_VIDEO_DEV=y even though it's not
necessarily so.
The problem in alsa-driver's build is that SND_FM801_TEA575X_BOOL is
evaluated after SND_FM801 and SND_FM801_TEA575X because the former is
an option. In acinclude.m4, the whole checks of options are done
after cards.
Maybe a better way would be to change acinclude.m4 like:
CARDS="xxx yyy ..."
OPTIONS="aaa bbb ..."
ac_snd_config_exists () {
# check whether $1 is in cards or options
}
# then check each card/option in the order appearing in
# Kconfig
if ac_snd_config_exists ad1816a; then
....
fi
if ac_snd_config_exists ad1816a; then
....
fi
