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);
};
