From cdcb19219714c796ddef1202e952566c5f86354d Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 28 Jul 2005 23:09:40 +0200 Subject: [PATCH] [PATCH] I2C: inline i2c_adapter_id We could inline i2c_adapter_id, as it is really, really short. Doing so saves a few bytes both in i2c-core and in the drivers using this function. before after diff drivers/hwmon/adm1026.ko 41344 41305 -39 drivers/hwmon/asb100.ko 27325 27246 -79 drivers/hwmon/gl518sm.ko 20824 20785 -39 drivers/hwmon/it87.ko 26419 26380 -39 drivers/hwmon/lm78.ko 21424 21385 -39 drivers/hwmon/lm85.ko 41034 40939 -95 drivers/hwmon/w83781d.ko 39561 39514 -47 drivers/hwmon/w83792d.ko 32979 32932 -47 drivers/i2c/i2c-core.ko 24708 24531 -177 Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman --- drivers/i2c/i2c-core.c | 9 --------- include/linux/i2c.h | 10 ++++++---- 2 files changed, 6 insertions(+), 13 deletions(-) diff --git a/drivers/i2c/i2c-core.c b/drivers/i2c/i2c-core.c index b0bceb2fb8b1..20f92e355f56 100644 --- a/drivers/i2c/i2c-core.c +++ b/drivers/i2c/i2c-core.c @@ -759,14 +759,6 @@ int i2c_probe(struct i2c_adapter *adapter, return 0; } -/* - * return id number for a specific adapter - */ -int i2c_adapter_id(struct i2c_adapter *adap) -{ - return adap->nr; -} - struct i2c_adapter* i2c_get_adapter(int id) { struct i2c_adapter *adapter; @@ -1196,7 +1188,6 @@ EXPORT_SYMBOL(i2c_master_send); EXPORT_SYMBOL(i2c_master_recv); EXPORT_SYMBOL(i2c_control); EXPORT_SYMBOL(i2c_transfer); -EXPORT_SYMBOL(i2c_adapter_id); EXPORT_SYMBOL(i2c_get_adapter); EXPORT_SYMBOL(i2c_put_adapter); EXPORT_SYMBOL(i2c_probe); diff --git a/include/linux/i2c.h b/include/linux/i2c.h index da4faa016b17..ad1c0fb164bc 100644 --- a/include/linux/i2c.h +++ b/include/linux/i2c.h @@ -364,10 +364,6 @@ extern int i2c_probe(struct i2c_adapter *adapter, */ extern int i2c_control(struct i2c_client *,unsigned int, unsigned long); -/* This call returns a unique low identifier for each registered adapter, - * or -1 if the adapter was not registered. - */ -extern int i2c_adapter_id(struct i2c_adapter *adap); extern struct i2c_adapter* i2c_get_adapter(int id); extern void i2c_put_adapter(struct i2c_adapter *adap); @@ -384,6 +380,12 @@ static inline int i2c_check_functionality(struct i2c_adapter *adap, u32 func) return (func & i2c_get_functionality(adap)) == func; } +/* Return id number for a specific adapter */ +static inline int i2c_adapter_id(struct i2c_adapter *adap) +{ + return adap->nr; +} + /* * I2C Message - used for pure i2c transaction, also from /dev interface */ -- 2.30.2
