void (* remove_dev) (struct device *dev, struct subsys_interface *sif);
}; Members
- name
name of the device function
- subsys
subsytem of the devices to attach to

Description
Simple interfaces attached to a subsystem. Multiple interfaces can
attach to a subsystem and its devices. Unlike drivers, they do not
exclusively claim or control devices. Interfaces usually represent
a specific functionality of a subsystem/class of devices.
