Subject: snd-pcsp: Disable autoload
Forwarded: not-needed
Bug-Debian: https://bugs.debian.org/697709

There are two drivers claiming the platform:pcspkr device:
- pcspkr creates an input(!) device that can only beep
- snd-pcsp creates an equivalent input device plus a PCM device that can
  play barely recognisable renditions of sampled sound

snd-pcsp is blacklisted by the alsa-base package, but not everyone
installs that.  On PCs where no sound is wanted at all, both drivers
will still be loaded and one or other will complain that it couldn't
claim the relevant I/O range.

In case anyone finds snd-pcsp useful, we continue to build it.  But
remove the alias, to ensure it's not loaded where it's not wanted.
