TRANSPORT_CLASS_REGI(9) 				   Device drivers infrastructure				   TRANSPORT_CLASS_REGI(9)

NAME

       transport_class_register - register an initial transport class

SYNOPSIS

       int transport_class_register(struct transport_class * tclass);

ARGUMENTS

       tclass
	   a pointer to the transport class structure to be initialised

DESCRIPTION

       The transport class contains an embedded class which is used to identify it. The caller should initialise this structure with zeros and
       then generic class must have been initialised with the actual transport class unique name. There's a macro DECLARE_TRANSPORT_CLASS to do
       this (declared classes still must be registered).

       Returns 0 on success or error on failure.

NAME

       device_create - creates a device and registers it with sysfs

SYNOPSIS

       struct device * device_create(struct class * class, struct device * parent, dev_t devt, void * drvdata, const char * fmt, ...);

ARGUMENTS

       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

       ...
	   variable arguments

DESCRIPTION

       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.
