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/soc/codecs/wm8741.c | 606 -------------------------------- 1 file changed, 606 deletions(-) delete mode 100644 ANDROID_3.4.5/sound/soc/codecs/wm8741.c (limited to 'ANDROID_3.4.5/sound/soc/codecs/wm8741.c') diff --git a/ANDROID_3.4.5/sound/soc/codecs/wm8741.c b/ANDROID_3.4.5/sound/soc/codecs/wm8741.c deleted file mode 100644 index 3941f50b..00000000 --- a/ANDROID_3.4.5/sound/soc/codecs/wm8741.c +++ /dev/null @@ -1,606 +0,0 @@ -/* - * wm8741.c -- WM8741 ALSA SoC Audio driver - * - * Copyright 2010 Wolfson Microelectronics plc - * - * Author: Ian Lartey - * - * - * This program is free software;
