ALSA: hdspm - Provide unique driver id based on card serial
Before, /proc/asound looked like this:
2 [Default ]: HDSPM - RME RayDAT_f1cd85
RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18
In case of a second HDSPM card, its name would be Default_1. This is
cumbersome, because the order of the cards isn't stable across reboots.
To help userspace tools referring to the correct card, this commit
provides a unique id for each card:
2 [HDSPMxf1cd85 ]: HDSPM - RME RayDAT_f1cd85
RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18
In this example, userspace (configuration files) would then use
hw:HDSPMxf1cd85 to choose the right card.
The serial is masked to 24bits, so this string is always shorter than
sixteen chars.
