<pre>ID_ID in udev will no longer append the ALSA "id" sysattr. This means ID_ID
will change to a new string after this update, but no longer be system unique
for USB. (It is theoretically not system unique for firewire already, since
broken devices can ship with a duplicate guid and no checking is done.)
The ALSA id sysattr is derived from some internal properties of the device by
the kernel. It is actually a read/write attribute, but ALSA enforces uniqueness
systemwide. This means that currently, ID_ID is enumeration dependent in the
case of multiple identical hardware.

This is essentially a revert of systemd
