DEVICE_CREATE(9) Device drivers infrastructure DEVICE_CREATE(9)NAME
device_create - creates a device and registers it with sysfs
struct device * device_create(struct class * class, struct device * parent, dev_t devt, void * drvdata, const char * fmt, ...);
pointer to the struct class that this device should be registered to
pointer to the parent struct device of this new device, if any
the dev_t for the char device to be added
the data to be added to the device for callbacks
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.
the struct class passed to this function must have previously been created with a call to class_create.
