/**

 * struct device_driver - The basic device driver structure
 * @name:    Name of the device driver.
 * @bus:    The bus which the device of this driver belongs to.
 * @owner:    The module owner.
 * @mod_name:    Used for built-in modules.
 * @suppress_bind_attrs: Disables bind/unbind via sysfs.
 * @of_match_table: The open firmware table.
 * @probe:    Called to query the existence of a specific device,
 *        whether this driver can work with it, and bind the driver
 *        to a specific device.
 * @remove:    Called when the device is removed from the system to
 *        unbind a device from this driver.
 * @shutdown:    Called at shut-down time to quiesce the device.
 * @suspend:    Called to put the device to sleep mode. Usually to a
 *        low power state.
 * @resume:    Called to bring a device from sleep mode.
 * @groups:    Default attributes that get created by the driver core
 *        automatically.
 * @pm:        Power management operations of the device which matched
 *        this driver.
 * @p:        Driver core's private data, no one other than the driver
 *        core can touch this.
 *
 * The device driver-model tracks all of the drivers known to the system.
 * The main reason for this tracking is to enable the driver core to match
 * up drivers with new devices. Once drivers are known objects within the
 * system, however, a number of other things become possible. Device drivers
 * can export information and configuration variables that are independent
 * of any specific device.
