The error handling path of mpc52xx_lpbfifo_probe() and a request_irq() is
not balanced by a corresponding free_irq().

Add the missing call, as already done in the remove function.

Another strange thing is that the remove function has:
        /* Release the bestcomm transmit task */
        free_irq(bcom_get_task_irq(lpbfifo.bcom_tx_task), &lpbfifo);
but I've not been able to find a corresponding request_irq().

Is it dead code? Is there something missing in the probe?
(...Is it working?...)
