From dc0a50afa67c3dbd51211881b7568917dbbc6861 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 12 Apr 2011 11:40:36 -0600 Subject: [PATCH] ASoC: Tegra: Rename harmony.c to tegra_wm8903.c Soon, this machine driver will be updated to handle a number of Tegra boards using the WM8903 codec. Rename the file in advance to reflect this. Fix the content of tegra_wm8903.c to match the rename; replace references to Harmony board with something more generic. * s/struct tegra_harmony/struct tegra_wm8903/ * s/harmony/machine/ # variable name * Similar rename for some functions * Similar comment fix * Similar MODULE_DESCRIPTION fix Signed-off-by: Stephen Warren Acked-by: Liam Girdwood Signed-off-by: Mark Brown --- sound/soc/tegra/Kconfig | 9 +- sound/soc/tegra/Makefile | 4 +- sound/soc/tegra/{harmony.c => tegra_wm8903.c} | 157 +++++++++--------- 3 files changed, 86 insertions(+), 84 deletions(-) rename sound/soc/tegra/{harmony.c => tegra_wm8903.c} (63%) diff --git a/sound/soc/tegra/Kconfig b/sound/soc/tegra/Kconfig index 66b504f06c23..9e53fec52d60 100644 --- a/sound/soc/tegra/Kconfig +++ b/sound/soc/tegra/Kconfig @@ -14,13 +14,14 @@ config SND_TEGRA_SOC_I2S Tegra I2S interface.
