From 58a7371a4dd9d03f77265ee2784781fc39096136 Mon Sep 17 00:00:00 2001 From: Bo Shen Date: Mon, 15 Oct 2012 15:51:17 +0800 Subject: i2c: i2c-gpio: fix name issue with multiple i2c gpio nodes When having multiple i2c-gpio nodes, the name for each is same. So add the patch to fix it. The adap->name printing information was added by myself without this patch the log information is as following ---<8--- adap->name = i2c-gpio-1 i2c-gpio i2c.2: using pins 30 (SDA) and 31 (SCL) adap->name = i2c-gpio-1 i2c-gpio i2c.3: using pins 64 (SDA) and 65 (SCL) --->8--- with this patch, the log information is as following ---<8--- adap->name = i2c.2 i2c-gpio i2c.2: using pins 30 (SDA) and 31 (SCL) adap->name = i2c.3 i2c-gpio i2c.3: using pins 64 (SDA) and 65 (SCL) --->8--- Signed-off-by: Bo Shen Reviewed-by: Stephen Warren [wsa: minor fixes to the commit mesage] Signed-off-by: Wolfram Sang --- drivers/i2c/busses/i2c-gpio.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'drivers') diff --git a/drivers/i2c/busses/i2c-gpio.c b/drivers/i2c/busses/i2c-gpio.c index e62d2d938628..257299a92df3 100644 --- a/drivers/i2c/busses/i2c-gpio.c +++ b/drivers/i2c/busses/i2c-gpio.c @@ -184,7 +184,11 @@ static int __devinit i2c_gpio_probe(struct platform_device *pdev) bit_data->data = pdata; adap->owner = THIS_MODULE; - snprintf(adap->name, sizeof(adap->name), "i2c-gpio%d", pdev->id); + if (pdev->dev.of_node) + strlcpy(adap->name, dev_name(&pdev->dev), sizeof(adap->name)); + else + snprintf(adap->name, sizeof(adap->name), "i2c-gpio%d", pdev->id); + adap->algo_data = bit_data; adap->class = I2C_CLASS_HWMON | I2C_CLASS_SPD; adap->dev.parent = &pdev->dev; -- cgit v1.2.3
