NAME

struct_subsys_interface - interfaces to device functions

SYNOPSIS

struct subsys_interface {


  const char * name;


  struct bus_type * subsys;


  struct list_head node;


  int (* add_dev) (struct device *dev, struct subsys_interface *sif);


  void (* remove_dev) (struct device *dev, struct subsys_interface *sif);
};
