From 5be509576cf634ad384025f50fc4fcb941d14256 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 15 Mar 2017 04:44:00 +0000 Subject: [PATCH] ASoC: simple-card: add new simple_priv_to_card() macro Current simple card driver is directly calling priv->snd_card everywhere, but it makes unreadable code. Let's use simple_priv_to_card() macro for it Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- sound/soc/generic/simple-card.c | 41 ++++++++++++++++++--------------- 1 file changed, 23 insertions(+), 18 deletions(-) diff --git a/sound/soc/generic/simple-card.c b/sound/soc/generic/simple-card.c index 9ad05e237ee0..948f3ba02d12 100644 --- a/sound/soc/generic/simple-card.c +++ b/sound/soc/generic/simple-card.c @@ -40,9 +40,10 @@ struct simple_card_data { struct snd_soc_dai_link *dai_link; }; -#define simple_priv_to_dev(priv) ((priv)->snd_card.dev) -#define simple_priv_to_link(priv, i) ((priv)->snd_card.dai_link + (i)) +#define simple_priv_to_card(priv) (&(priv)->snd_card) #define simple_priv_to_props(priv, i) ((priv)->dai_props + (i)) +#define simple_priv_to_dev(priv) (simple_priv_to_card(priv)->dev) +#define simple_priv_to_link(priv, i) (simple_priv_to_card(priv)->dai_link + (i)) #define DAI "sound-dai" #define CELL "#sound-dai-cells" @@ -323,6 +324,7 @@ static int asoc_simple_card_parse_aux_devs(struct device_node *node, { struct device *dev = simple_priv_to_dev(priv); struct device_node *aux_node; + struct snd_soc_card *card = simple_priv_to_card(priv); int i, n, len; if (!of_find_property(node, PREFIX "aux-devs", &len)) @@ -332,19 +334,19 @@ static int asoc_simple_card_parse_aux_devs(struct device_node *node, if (n <= 0) return -EINVAL; - priv->snd_card.aux_dev = devm_kzalloc(dev, - n * sizeof(*priv->snd_card.aux_dev), GFP_KERNEL); - if (!priv->snd_card.aux_dev) + card->aux_dev = devm_kzalloc(dev, + n * sizeof(*card->aux_dev), GFP_KERNEL); + if (!card->aux_dev) return -ENOMEM; for (i = 0; i < n; i++) { aux_node = of_parse_phandle(node, PREFIX "aux-devs", i); if (!aux_node) return -EINVAL; - priv->snd_card.aux_dev[i].codec_of_node = aux_node; + card->aux_dev[i].codec_of_node = aux_node; } - priv->snd_card.num_aux_devs = n; + card->num_aux_devs = n; return 0; } @@ -352,6 +354,7 @@ static int asoc_simple_card_parse_of(struct device_node *node, struct simple_card_data *priv) { struct device *dev = simple_priv_to_dev(priv); + struct snd_soc_card *card = simple_priv_to_card(priv); struct device_node *dai_link; int ret; @@ -362,7 +365,7 @@ static int asoc_simple_card_parse_of(struct device_node *node, /* The off-codec widgets */ if (of_property_read_bool(node, PREFIX "widgets")) { - ret = snd_soc_of_parse_audio_simple_widgets(&priv->snd_card, + ret = snd_soc_of_parse_audio_simple_widgets(card, PREFIX "widgets"); if (ret) goto card_parse_end; @@ -370,7 +373,7 @@ static int asoc_simple_card_parse_of(struct device_node *node, /* DAPM routes */ if (of_property_read_bool(node, PREFIX "routing")) { - ret = snd_soc_of_parse_audio_routing(&priv->snd_card, + ret = snd_soc_of_parse_audio_routing(card, PREFIX "routing"); if (ret) goto card_parse_end; @@ -401,7 +404,7 @@ static int asoc_simple_card_parse_of(struct device_node *node, goto card_parse_end; } - ret = asoc_simple_card_parse_card_name(&priv->snd_card, PREFIX); + ret = asoc_simple_card_parse_card_name(card, PREFIX); if (ret < 0) goto card_parse_end; @@ -420,6 +423,7 @@ static int asoc_simple_card_probe(struct platform_device *pdev) struct simple_dai_props *dai_props; struct device *dev = &pdev->dev; struct device_node *np = dev->of_node; + struct snd_soc_card *card; int num, ret; /* Get the number of DAI links */ @@ -442,10 +446,11 @@ static int asoc_simple_card_probe(struct platform_device *pdev) priv->dai_link = dai_link; /* Init snd_soc_card */ - priv->snd_card.owner = THIS_MODULE; - priv->snd_card.dev = dev; - priv->snd_card.dai_link = priv->dai_link; - priv->snd_card.num_links = num; + card = simple_priv_to_card(priv); + card->owner = THIS_MODULE; + card->dev = dev; + card->dai_link = priv->dai_link; + card->num_links = num; if (np && of_device_is_available(np)) { @@ -474,7 +479,7 @@ static int asoc_simple_card_probe(struct platform_device *pdev) return -EINVAL; } - priv->snd_card.name = (cinfo->card) ? cinfo->card : cinfo->name; + card->name = (cinfo->card) ? cinfo->card : cinfo->name; dai_link->name = cinfo->name; dai_link->stream_name = cinfo->name; dai_link->platform_name = cinfo->platform; @@ -489,13 +494,13 @@ static int asoc_simple_card_probe(struct platform_device *pdev) sizeof(priv->dai_props->codec_dai)); } - snd_soc_card_set_drvdata(&priv->snd_card, priv); + snd_soc_card_set_drvdata(card, priv); - ret = devm_snd_soc_register_card(dev, &priv->snd_card); + ret = devm_snd_soc_register_card(dev, card); if (ret >= 0) return ret; err: - asoc_simple_card_clean_reference(&priv->snd_card); + asoc_simple_card_clean_reference(card); return ret; }
