struct device *device_create(struct class *class, struct device *parent, dev_t devt, void *drvdata,

/**

* device_create - creates a device and registers it with sysfs

* @class: pointer to the struct class that this device should be registered to

* @parent: pointer to the parent struct device of this new device, if any

* @devt: the dev_t for the char device to be added

* @drvdata: the data to be added to the device for callbacks

* @fmt: string for the device's name

*

* This function can be used by char device classes. A struct device

* will be created in sysfs, registered to the specified class.

*

* A "dev" file will be created, showing the dev_t for the device, if

* the dev_t is not 0,0.

* If a pointer to a parent struct device is passed in, the newly created

* struct device will be a child of that device in sysfs.

* The pointer to the struct device will be returned from the call.

* Any further sysfs files that might be required can be created using this

* pointer.

*

* Returns &struct device pointer on success, or ERR_PTR() on error.

*

* Note: the struct class passed to this function must have previously

* been created with a call to class_create().
