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/wm8711.c | 529 -------------------------------- 1 file changed, 529 deletions(-) delete mode 100644 ANDROID_3.4.5/sound/soc/codecs/wm8711.c (limited to 'ANDROID_3.4.5/sound/soc/codecs/wm8711.c') diff --git a/ANDROID_3.4.5/sound/soc/codecs/wm8711.c b/ANDROID_3.4.5/sound/soc/codecs/wm8711.c deleted file mode 100644 index 0b76d1dc..00000000 --- a/ANDROID_3.4.5/sound/soc/codecs/wm8711.c +++ /dev/null @@ -1,529 +0,0 @@ -/* - * wm8711.c -- WM8711 ALSA SoC Audio driver - * - * Copyright 2006 Wolfson Microelectronics - * - * Author: Mike Arthur - * - * Based on wm8731.c by Richard Purdie - * - * This program is free software;
