> Subject: [PATCH] ivi-shell: rename ivi_controller_interface
> 
> The name of ivi_controller_interface is changed to ivi_layout_interface
> with this patch.
> 
> This name is better suited to the interface, because it is implemented
> in ivi-layout.c and its methods are linked to ivi_layout* functions.
> 
> Furthermore, the controller modules (e.g. hmi-controller) are the users
> of this interface and they have their own interfaces,
> which are called *_controller_interface,
> e.g.: ivi_hmi_controller_interface.
> 
> This causes confusion about the software architecture.
