"Unknown model for AD1988" --> AD1988B

[Dâniel Fraga]

Linux 2.6.20
x86_64
Motherboard Asus M2N-E

	alsamixer shows the following:

Card: HDA NVidia
Chip: Analog Devices AD1988B

	Everything works fine, except that the kernel initial boot
messages show the following:

hda_codec: Unknown model for AD1988, trying auto-probe from BIOS...
alsactl: set_control:991: warning: name mismatch (Surround Playback Volume/Front Playback Switch) for control #2
alsactl: set_control:993: warning: index mismatch (0/0) for control #2
alsactl: set_control:1106: bad control.2.value.0 content

	Should I worry about it?

It shouldn't appear at the second boot again.  If this appears more
times, something is unstable, for example, probing of the mixer
controls isn't constantly done.  Otherwise, it's harmless.
