[ALSA] ad1816a: Fix modprobe snd_mpu401 && modprobe snd_ad1816a
The ad1816a driver fails if the mpu401 driver has been loaded first. This patch against linux 2.6.20 fixes it by just ignoring the MPU-401 device in that case, so that the rest of the sound card can be used. The ad1816a driver already handles the MPU-401 device being unavailable due to lack of resources in the same way.
