From 83e8ad6984dccd6d848ac91ba0df379ff968180b Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 12 Dec 2005 09:30:43 +0100 Subject: [PATCH] [ALSA] seq: remove struct snd_seq_client_callback The fields of struct snd_seq_client_callback either aren't used or are always set to the same value, so we can get rid of it altogether.
