ieee1394/ohci1394: CycleTooLong interrupt management
This patch modifies the ohci1394.c file to enable and manage the "cycle too
long" interrupt.
If this interrupt occurs, the "LinkControl.CycleMaster" bit of the host
controller is reseted. This implies, that the host controller does not send
"cycle start" packet anymore freezing then the isochronous communication.
The management of the interrupt added by the patch is that when the interrupt
occurs, the OHCI irq handler prints a kernel log warning and then sets the
"LinkControl.CycleMaster" bit again resuming the isochronous communication.
