This bug resulted in output like this: i2c Xy2�0: adapter [SMBus I801 adapter at 1880] unregistered The right output would be: i2c i2c-0: adapter [SMBus I801 adapter at 1880] unregistered Signed-off-by: Thadeu Lima de Souza Cascardo Signed-off-by: Jean Delvare --- drivers/i2c/i2c-core.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/i2c/i2c-core.c b/drivers/i2c/i2c-core.c index d610e995..10be7b5 100644 --- a/drivers/i2c/i2c-core.c +++ b/drivers/i2c/i2c-core.c @@ -843,6 +843,9 @@ int i2c_del_adapter(struct i2c_adapter *adap) adap->dev.parent); #endif + /* device name is gone after device_unregister */ + dev_dbg(&adap->dev, "adapter [%s] unregistered\n", adap->name); + /* clean up the sysfs representation */ init_completion(&adap->dev_released); device_unregister(&adap->dev); @@ -855,8 +858,6 @@ int i2c_del_adapter(struct i2c_adapter *adap) idr_remove(&i2c_adapter_idr, adap->nr); mutex_unlock(&core_lock); - dev_dbg(&adap->dev, "adapter [%s] unregistered\n", adap->name); - /* Clear the device structure in case this adapter is ever going to be added again */ memset(&adap->dev, 0, sizeof(adap->dev)); -- 2.7.4
