A new randconfig build failure shows that the fsl-asoc-card module must not be built-in when the AC97 driver is a loadable module:
sound/built-in.o: In function `fsl_asoc_card_late_probe': :(.text+0x571d8): undefined reference to `snd_ac97_update_bits'
I couldn't come up with a nice solution, so this adds another dependency on "X || !X", which is the Kconfig way of saying that we have an optional dependency on something that might be a loadable module.
Signed-off-by: Arnd Bergmann arnd@arndb.de Fixes: 50760cad9de9 ("ASoC: fsl-asoc-card: add AC'97 support") --- The commit that introduced this was merged for 4.4-rc1, so we might want the fix to go into 4.4 as well.
