73  * This IOCTL is used to associate the current file descriptor with a
74  * FW Client (given by UUID). This opens a communication channel
75  * between a host client and a FW client. From this point every read and write
76  * will communicate with the associated FW client.
77  * Only in close() (file_operation release()) the communication between
78  * the clients is disconnected
79  *
80  * The IOCTL argument is a struct with a union that contains
81  * the input parameter and the output parameter for this IOCTL.
82  *
83  * The input parameter is UUID of the FW Client.
84  * The output parameter is the properties of the FW client
85  * (FW protocol version and max message size).
