Instead of creating attributes one by one, define attribute_group array and attach it to bus->dev_groups, so that all needed attributes are created automatically when a new device is registered on the bus. Also switch to using standard DEVICE_ATTR_RO() macros. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
