dsi_packet_sent_handler_vp() and dsi_packet_sent_handler_l4() currently receive the completion parameter as their argument. This is not sufficient information to differentiate between DSI1 and DSI2 platform devices. Pass the struct "dsi_packet_sent_handler_data" to the packet_sent_handler isrs, these contain the platform_device pointer of the DSI device and the pointer to the completion struct.
