[PATCH] Persistent sound device udi

[Jürg Billeter]

Hi

The ALSA and OSS sound devices currently include the card number in the
udi. This is problematic as the card numbers are not guaranteed to be
persistent (and really change across reboots). Unfortunately ALSA (resp.
the hardware) doesn't provide serial numbers for sound devices. So the
attached patch just removes the card number to get a persistent udi at
least in the most common cases.

Regards,

Jürg
