From b86c87288c2205376ee213d6a03ac9422faf014a Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 13 Jul 2009 13:50:17 +0200 Subject: [PATCH] sound: seq_midi: do not send MIDI reset when closing Sending a MIDI reset message when closing a port is wrong because we only want to shut the device up, not to reset all settings. Furthermore, many devices ignore this message. Fortunately, the RawMIDI layer already shuts the device up, so we can ignore this matter here.
