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/pci/ice1712/ak4xxx.c | 196 ------------------------------- 1 file changed, 196 deletions(-) delete mode 100644 ANDROID_3.4.5/sound/pci/ice1712/ak4xxx.c (limited to 'ANDROID_3.4.5/sound/pci/ice1712/ak4xxx.c') diff --git a/ANDROID_3.4.5/sound/pci/ice1712/ak4xxx.c b/ANDROID_3.4.5/sound/pci/ice1712/ak4xxx.c deleted file mode 100644 index 3981823f..00000000 --- a/ANDROID_3.4.5/sound/pci/ice1712/ak4xxx.c +++ /dev/null @@ -1,196 +0,0 @@ -/* - * ALSA driver for ICEnsemble ICE1712 (Envy24) - * - * AK4524 / AK4528 / AK4529 / AK4355 / AK4381 interface - * - * Copyright (c) 2000 Jaroslav Kysela - * - * 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.
