dev_printk and new-style class devices
As the new-style class devices (as opposed to old-style struct class_device) are becoming more widely used, I noticed that the dev_printk-based functions are not working properly with these. New-style class devices have no driver nor bus, almost by definition, and as a result dev_driver_string(), which is used as the first parameter of dev_printk, resolves to an empty string. This causes entries like the following to show in my logs: i2c-2: adapter [SMBus stub driver] registered Notice the unaesthetical leading whitespace. In order to fix this problem, I suggest that we extend dev_driver_string to deal with new-style class devices: Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
