From 075413966a6ea389f78f4cc2e957708c1d6db8c5 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 19 Apr 2011 15:25:09 -0600 Subject: ASoC: Tegra: Don't return mclk_changed from utils_set_rate Only the clock programming code needs to know whether the clocks changed, and that is encapsulated within tegra_asoc_utils_set_rate(). The machine driver's call to snd_soc_dai_set_sysclk(codec_dai, ...) is safe irrespective of whether the clocks changed. (Applying Mark's TrimSlice review comments to the existing driver) Signed-off-by: Stephen Warren Acked-by: Liam Girdwood Signed-off-by: Mark Brown --- sound/soc/tegra/tegra_wm8903.c | 17 +++++++---------- 1 file changed, 7 insertions(+), 10 deletions(-) (limited to 'sound/soc/tegra/tegra_wm8903.c') diff --git a/sound/soc/tegra/tegra_wm8903.c b/sound/soc/tegra/tegra_wm8903.c index b12b1fd1cb6e..988ff504dd59 100644 --- a/sound/soc/tegra/tegra_wm8903.c +++ b/sound/soc/tegra/tegra_wm8903.c @@ -72,7 +72,7 @@ static int tegra_wm8903_hw_params(struct snd_pcm_substream *substream, struct snd_soc_codec *codec = rtd->codec; struct snd_soc_card *card = codec->card; struct tegra_wm8903 *machine = snd_soc_card_get_drvdata(card); - int srate, mclk, mclk_change; + int srate, mclk; int err; srate = params_rate(params); @@ -90,8 +90,7 @@ static int tegra_wm8903_hw_params(struct snd_pcm_substream *substream, while (mclk < 6000000) mclk *= 2; - err = tegra_asoc_utils_set_rate(&machine->util_data, srate, mclk, - &mclk_change); + err = tegra_asoc_utils_set_rate(&machine->util_data, srate, mclk); if (err < 0) { dev_err(card->dev, "Can't configure clocks\n"); return err; @@ -115,13 +114,11 @@ static int tegra_wm8903_hw_params(struct snd_pcm_substream *substream, return err; } - if (mclk_change) { - err = snd_soc_dai_set_sysclk(codec_dai, 0, mclk, - SND_SOC_CLOCK_IN); - if (err < 0) { - dev_err(card->dev, "codec_dai clock not set\n"); - return err; - } + err = snd_soc_dai_set_sysclk(codec_dai, 0, mclk, + SND_SOC_CLOCK_IN); + if (err < 0) { + dev_err(card->dev, "codec_dai clock not set\n"); + return err; } return 0; -- cgit v1.2.1
