No error condition is checked, and the device is started. Later on, when irq is serviced, a NULL pointer dereference occurs. Also, the isr routine must be registered only if no error occurs, otherwise the isr triggers without the proper setup, and the kernel oops again. To prevent this, the error condition is checked, and the streamon function exits with error. Also the isr registration call is moved after the setup procedure is completed.
