From foo@baz Tue Dec 6 15:35:16 2005 Date: Tue, 6 Dec 2005 15:33:15 -0800 From: Greg Kroah-Hartman Subject: I2C: Make i2c_add_driver automatically set the proper module owner This prevents i2c drivers from messing up and forgetting to set the module owner of their driver. It also reduces the size of their drivers by one line :) Signed-off-by: Greg Kroah-Hartman Cc: Jean Delvare --- drivers/i2c/i2c-core.c | 5 +++-- include/linux/i2c.h | 7 ++++++- 2 files changed, 9 insertions(+), 3 deletions(-) --- gregkh-2.6.orig/drivers/i2c/i2c-core.c +++ gregkh-2.6/drivers/i2c/i2c-core.c @@ -287,7 +287,7 @@ int i2c_del_adapter(struct i2c_adapter * * chips. */ -int i2c_add_driver(struct i2c_driver *driver) +int i2c_register_driver(struct module *owner, struct i2c_driver *driver) { struct list_head *item; struct i2c_adapter *adapter; @@ -296,6 +296,7 @@ int i2c_add_driver(struct i2c_driver *dr down(&core_lists); /* add the driver to the list of i2c drivers in the driver core */ + driver->driver.owner = owner; driver->driver.bus = &i2c_bus_type; driver->driver.probe = i2c_device_probe; driver->driver.remove = i2c_device_remove; @@ -319,6 +320,7 @@ int i2c_add_driver(struct i2c_driver *dr up(&core_lists); return res; } +EXPORT_SYMBOL(i2c_register_driver); int i2c_del_driver(struct i2c_driver *driver) { @@ -1132,7 +1134,6 @@ EXPORT_SYMBOL_GPL(i2c_bus_type); EXPORT_SYMBOL(i2c_add_adapter); EXPORT_SYMBOL(i2c_del_adapter); -EXPORT_SYMBOL(i2c_add_driver); EXPORT_SYMBOL(i2c_del_driver); EXPORT_SYMBOL(i2c_attach_client); EXPORT_SYMBOL(i2c_detach_client); --- gregkh-2.6.orig/include/linux/i2c.h +++ gregkh-2.6/include/linux/i2c.h @@ -291,9 +291,14 @@ struct i2c_client_address_data { extern int i2c_add_adapter(struct i2c_adapter *); extern int i2c_del_adapter(struct i2c_adapter *); -extern int i2c_add_driver(struct i2c_driver *); +extern int i2c_register_driver(struct module *, struct i2c_driver *); extern int i2c_del_driver(struct i2c_driver *); +static inline int i2c_add_driver(struct i2c_driver *driver) +{ + return i2c_register_driver(THIS_MODULE, driver); +} + extern int i2c_attach_client(struct i2c_client *); extern int i2c_detach_client(struct i2c_client *);
