From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/sound/drivers/opl3/opl3_seq.c | 298 ---------------------------- 1 file changed, 298 deletions(-) delete mode 100644 ANDROID_3.4.5/sound/drivers/opl3/opl3_seq.c (limited to 'ANDROID_3.4.5/sound/drivers/opl3/opl3_seq.c') diff --git a/ANDROID_3.4.5/sound/drivers/opl3/opl3_seq.c b/ANDROID_3.4.5/sound/drivers/opl3/opl3_seq.c deleted file mode 100644 index 68399538..00000000 --- a/ANDROID_3.4.5/sound/drivers/opl3/opl3_seq.c +++ /dev/null @@ -1,298 +0,0 @@ -/* - * Copyright (c) by Uros Bizjak - * - * Midi Sequencer interface routines for OPL2/OPL3/OPL4 FM - * - * OPL2/3 FM instrument loader: - * alsa-tools/seq/sbiload/ - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
