[PATCH]snd_seq_midi_event: Unknown symbol cleanup_module [PATCH] Unknown symbol init_module and cleanup_module in snd_seq_midi_event

[Mikael Magnusson]

I had problems loading the snd_seq_midi_event compiled from ALSA cvs. 
I'm using Debian Sarge with the following kernel packages:

kernel-headers-2.6.10-1-k7 2.6.10-4
kernel-image-2.6.10-1-k7 2.6.10-4

The problem was caused by undefined symbols in snd_seq_midi_event.

  snd_seq_midi_event: Unknown symbol cleanup_module
  snd_seq_midi_event: Unknown symbol init_module

I solved it by adding an init and exit function to seq_midi_event.c. Is 
this a bug in ALSA or Debian?

Regards,
Mikael

I don't know.  At least, this is no problem on my SUSE system.

Anyway, adding them must be harmless, so I applied your patch.
Thanks.
