i2c: Do not use device name after device_unregister
dev_dbg outputs dev_name, which is released with device_unregister. 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 <cascardo@holoscopio.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
