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 <voice.shen@atmel.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> [wsa: minor fixes to the commit mesage] Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
